December 2018 crawl archive now available

The crawl archive for December 2018 is now available! It contains 3.1 billion web pages or 250 TiB of uncompressed content, crawled between December 9th and 19th.

The December crawl contains page captures of 735 million URLs not contained in any crawl archive before. New URLs stem from:

  • extracting and sampling URLs from sitemaps, RSS and Atom feeds if provided by hosts visited in prior crawls. Hosts are selected from the highest-ranking 60 million domains of the Aug/Sep/Oct 2018 webgraph data set
  • a breadth-first side crawl within a maximum of 6 links (“hops”) away from the home pages of the top 50 million domains of the webgraph dataset
  • a random sample of outlinks taken from WAT files of the November crawl
  • 30 million external links sampled from Wikipedia data dumps

Archive Location and Download

The December crawl archive is located in the commoncrawl bucket at crawl-data/CC-MAIN-2018-51/.

To assist with exploring and using the dataset, we provide gzipped files which list all segments, WARC, WAT and WET files.
By simply adding either s3://commoncrawl/ or https://data.commoncrawl.org/ to each line, you end up with the S3 and HTTP paths respectively.

Host- and Domain-Level Web Graphs Aug/Sep/Oct 2018

We are pleased to announce a new release of host-level and domain-level web graphs based on the published crawls of August, September and October 2018. Additional information about data formats, the processing pipeline, our objectives, and credits can be found in the announcements of prior webgraph releases (e.g., the Feb/Mar/Apr 2017 Webgraphs). You may also visit the projects cc-webgraph and cc-pyspark which host all scripts and tools required to construct the graphs.

Host-level graph

The graph consists of 903 million nodes and 5.25 billion edges and includes dangling nodes i.e. hosts that have not been crawled yet are pointed to from a link on a crawled page. There are 819 million dangling nodes (91%) and the largest strongly connected component contains only 60 million (6.5%) nodes. The host names are reversed and a leading www. is stripped: www.subdomain.example.com becomes com.example.subdomain.

You can download the graph and the ranks of all 903 million hosts from AWS S3 on the path s3://commoncrawl/projects/hyperlinkgraph/cc-main-2018-aug-sep-oct/host/. Alternatively, you can use https://data.commoncrawl.org/projects/hyperlinkgraph/cc-main-2018-aug-sep-oct/host/ as prefix to access the files from everywhere.

The following files and formats are provided:

Domain-level graph

The domain graph was built by aggregating the host graph on the level of pay-level domains (PLDs) based on the public suffix list maintained on publicsuffix.org.

The domain-level graph has 87 million nodes and 1.48 billion edges. 56% or 49 million nodes are dangling nodes, the largest strongly connected component covers 33.5 million or 38% of the nodes.

All files related to the domain graph are available on AWS S3 under s3://commoncrawl/projects/hyperlinkgraph/cc-main-2018-aug-sep-oct/domain/ resp. https://data.commoncrawl.org/projects/hyperlinkgraph/cc-main-2018-aug-sep-oct/domain/.

Thanks to the authors of the WebGraph framework, whose software made the computation of graph properties and ranks possible.

We hope the data will be useful for you to do any kind of research on ranking, graph analysis, link spam detection, etc. Let us know about your results via Common Crawl’s Google Group!

October 2018 crawl archive now available

The crawl archive for October 2018 is now available! It contains 3.0 billion web pages and 240 TiB of uncompressed content, crawled between October 15th and 24th.

The October crawl contains 600 million new URLs, not contained in any crawl archive before. New URLs stem from:

  • extracting and sampling URLs from sitemaps, RSS and Atom feeds if provided by hosts visited in prior crawls. Hosts are selected from the highest-ranking 60 million domains of the May/June/July 2018 webgraph data set
  • a breadth-first side crawl within a maximum of 10 links (“hops”) away from the home pages of the top 40 million domains of the webgraph dataset
  • a random sample of outlinks taken from WAT files of the September crawl
  • 15 million external links sampled from Wikipedia data dumps

Please note that the character set detection was not fully working for the first 13 segments of the October crawl – about 15% of the page captures in these segments have no charset and language assigned. More information is found in the bug report.

Archive Location and Download

The October crawl archive is located in the commoncrawl bucket at crawl-data/CC-MAIN-2018-43/.

To assist with exploring and using the dataset, we provide gzipped files which list all segments, WARC, WAT and WET files.
By simply adding either s3://commoncrawl/ or https://data.commoncrawl.org/ to each line, you end up with the S3 and HTTP paths respectively.

The Common Crawl URL Index for this crawl is available at: https://index.commoncrawl.org/CC-MAIN-2018-43/. Also the columnar index has been updated to contain this crawl.

Please donate to Common Crawl if you appreciate our free datasets! We’re also seeking corporate sponsors to partner with Common Crawl for our non-profit work in open data. Please contact [email protected] for sponsorship information.

September 2018 crawl archive now available

The crawl archive for September 2018 is now available! It contains 2.8 billion web pages and 220 TiB of uncompressed content, crawled between September 17th and 26th.

The following improvements and fixes to the data formats have been made:

  • the columnar index contains the content language of a web page as a new field. Please read the instructions below how to upgrade your tools to read newly added fields.
  • WARC revisit records (HTTP status 304) in the URL indexes do not include a field for the payload "digest" anymore. The corresponding column "content_digest" in the columnar index now contains null values.
  • we’ve fixed a bug in the WARC writer which added an extra line break (\r\n) between HTTP header and payload in WARC response record. See the announcement on our Google group for details. Thanks again to Greg Lindahl for discovering this bug!

The September crawl contains 500 million new URLs, not contained in any crawl archive before. New URLs stem from

  • the continued seed donation of URLs from mixnode.com
  • extracting and sampling URLs from sitemaps, RSS and Atom feeds if provided by hosts visited in prior crawls. Hosts are selected from the highest-ranking 60 million domains of the May/June/July 2018 webgraph data set
  • a breadth-first side crawl within a maximum of 6 links (“hops”) away from the home pages of the top 25 million domains of the webgraph dataset
  • a random sample taken from WAT files of the August crawl

New Fields in the Columnar URL Index

The columnar index has been updated to contain two new fields added to WARC and CDX files starting with the August crawl:

In addition, the column content_digest now contains null values.

The table schema in the cc-index-table project on github has been updated to reflect these changes.

Please follow the instructions below to upgrade to the new schema for Spark, Athena/Presto or Hive. If you do not want to use the new fields, no action is required, the tools should continue to work with the old schema.

Spark

The property spark.sql.parquet.mergeSchema must be set to true, e.g. by running the Spark job with the command

spark-submit --conf spark.sql.parquet.mergeSchema=true ...

Note that enabling schema merging has a negative impact on the performance of Spark jobs,
you may want to enable it only in case the new fields are required for your task.

Athena / Presto

Please create a new table using the updated schema. The old schema will continue to work but the new fields cannot be used. Further information can be found in the chapter about schema updates in the Athena documentation.

Hive

Schema evolution is supported since version 0.13. The procedure is essentially the same as for Athena – you need to drop and re-create the table with the updated schema only in case the new fields are used.

Archive Location and Download

The September crawl archive is located in the commoncrawl bucket at crawl-data/CC-MAIN-2018-39/.

To assist with exploring and using the dataset, we provide gzipped files which list all segments, WARC, WAT and WET files.
By simply adding either s3://commoncrawl/ or https://data.commoncrawl.org/ to each line, you end up with the S3 and HTTP paths respectively.

August Crawl Archive Introduces Language Annotations

The crawl archive for August 2018 is now available! It contains 2.65 billion web pages and 220 TiB of uncompressed content, crawled between August 14th and 22th. Together with an upgrade of the crawler software we’ve plugged in a language detector and now provide as annotation the language a web page is written in.

Please note that the WARC files of August 2018 (CC-MAIN-2018-34) are affected by a WARC format error and contain an extra \r\n between HTTP header and payload content. Also the given "Content-Length" is off by 2 bytes. For more information about this bug see this post on our user forum.

Language Annotations

We now run the Compact Language Detector 2 (CLD2) on HTML pages to identify the language of a document. CLD2 is able to identify 160 different languages and up to 3 languages per document. The detected languages resp. the ISO-639-3 code are shown in the URL index as a new field, e.g., "languages": "zho,eng". The WARC metadata records contain the full CLD2 response including scores and text coverage:

languages-cld2: {"reliable":true,"text-bytes":3783,"languages":[{"code":"zh","code-iso-639-3":"zho","text-covered":0.93,"score":1943.0,"name":"Chinese"},{"code":"en","code-iso-639-3":"eng","text-covered":0.05,"score":523.0,"name":"ENGLISH"}]}

On github you’ll find the Java bindings to the CLD2 native library and the distribution of the primary document languages as part of our crawl statistics.

Please note that the columnar index does not contain the detected languages for now. This requires a change of the table schema. We plan to add the new fields later after we’ve verified that an update of the schema does not break common tools (e.g., Spark or Presto/Athena) used to process the table.

Crawler Software Upgrade and Minor Changes to WARC Files

Our crawler has been upgraded and is now based on the most recent version of Apache Nutch (1.15). The source code can be found on github in our Nutch fork.

In conjunction with the crawler upgrade we made the following minor changes affecting the WARC record format of the crawl archives:

  • "HTTP 304 notmodified" responses are now stored as WARC revisit records in the "crawldiagnostics" subset along with 404s, redirects and other non-200 responses. For now the revisit records contain a payload digest although there is no payload sent together with HTTP 304 responses. The stupid reason is that the columnar index requires the digest field and we want to make sure that all tools continue to work as expected. The SHA-1 digest of an empty payload (zero bytes) is used for the revisit records.
  • All HTTP response headers are now preserved. As before, if the page content is truncated or was compressed or chunked during transfer, the headers "Content-Encoding", "Transfer-Encoding" and "Content-Length" need to be rewritten, otherwise WARC readers may fail reading the record payload. E.g., a page compressed on the HTTP protocol layer may have the following headers – the original headers are prefixed with X-Crawler-:
    X-Crawler-Content-Encoding: gzip
    X-Crawler-Content-Length: 2010
    Content-Length: 16125
    
  • The crawler may now also store pages fetched partially because of a network disconnect. These captures are marked as WARC-Truncated: disconnect in the WARC record header. Note that the crawler may also truncate the page payload because of a content limit (we store only 1 MB per page) or a time limit (after 10 minutes a page download is canceled).
  • the WARC record headers indicate still "WARC/1.0" although we follow the WARC specification, v1.1. While testing various WARC reader libraries we’ve found that at least two of them fail on records with a "WARC/1.1" header.

Please note that due to a bug the first two crawled segments are without robots.txt captures.

Host- and Domain-Level Web Graphs May/June/July 2018

We are pleased to announce a new release of host-level and domain-level web graphs based on the published crawls of May, June and July 2018. Additional information about data formats, the processing pipeline, our objectives, and credits can be found in the announcements of prior webgraph releases (e.g., Nov/Dec/Jan 2017-2018 Webgraphs).

Host-level graph

The graph consists of 886 million nodes and 5.4 billion edges and includes dangling nodes i.e. hosts that have not been crawled yet are pointed to from a link on a crawled page. There are 793 million dangling nodes (89.5%) and the largest strongly connected component contains only 67 million (7.5%) nodes. The host names are reversed and a leading www. is stripped: www.subdomain.example.com becomes com.example.subdomain.

You can download the graph and the ranks of all 886 million hosts from AWS S3 on the path s3://commoncrawl/projects/hyperlinkgraph/cc-main-2018-may-jun-jul/host/. Alternatively, you can use https://data.commoncrawl.org/projects/hyperlinkgraph/cc-main-2018-may-jun-jul/host/ as prefix to access the files from everywhere.

The following files and formats are provided:

Domain-level graph

The domain graph was built by aggregating the host graph on the level of pay-level domains (PLDs) based on the public suffix list maintained on publicsuffix.org.

The domain-level graph has 92 million nodes and 1.45 billion edges. 57% or 53 million nodes are dangling nodes, the largest strongly connected component covers 34 million or 37% of the nodes.

All files related to the domain graph are available on AWS S3 under s3://commoncrawl/projects/hyperlinkgraph/cc-main-2018-may-jun-jul/domain/ resp. https://data.commoncrawl.org/projects/hyperlinkgraph/cc-main-2018-may-jun-jul/domain/.

Thanks to the authors of the WebGraph framework, whose software made the computation of graph properties and ranks possible.

We hope the data will be useful for you to do any kind of research on ranking, graph analysis, link spam detection, etc. Let us know about your results via Common Crawl’s Google Group!

3.25 Billion Pages Crawled in July 2018

The crawl archive for July 2018 is now available! The archive is located in the commoncrawl bucket at crawl-data/CC-MAIN-2018-30/. It contains 3.25 billion web pages and 255 TiB of uncompressed content, crawled between July 15th and 23th.

The July crawl contains 625 million new URLs, not contained in any crawl archive before. New URLs are “mined” by

  • extracting and sampling URLs from sitemaps, RSS and Atom feeds if provided by hosts visited in prior crawls. Hosts are selected from the highest-ranking 60 million domains of the Feb/Mar/Apr 2018 webgraph data set
  • a breadth-first side crawl within a maximum of 6 links (“hops”) away from the home pages of the top 25 million hosts or top 25 million domains of the webgraph dataset
  • a random sample taken from WAT files of the June crawl

To assist with exploring and using the dataset, we provide gzipped files which list all segments, WARC, WAT and WET files.
By simply adding either s3://commoncrawl/ or https://data.commoncrawl.org/ to each line, you end up with the S3 and HTTP paths respectively.

June 2018 Crawl Archive Now Available

The crawl archive for June 2018 is now available! The archive is located in the commoncrawl bucket at crawl-data/CC-MAIN-2018-26/. It contains 3.05 billion web pages and 235 TiB of uncompressed content, crawled between June 18th and 25th.

The June crawl contains 700 million new URLs, not contained in any crawl archive before. New URLs are “mined” by

  • extracting and sampling URLs from sitemaps, RSS and Atom feeds if provided by hosts visited in prior crawls. Hosts are selected from the highest-ranking 60 million domains of the Feb/Mar/Apr 2018 webgraph data set
  • a breadth-first side crawl within a maximum of 4 links (“hops”) away from the home pages of the top 25 million hosts or top 25 million domains of the webgraph dataset
  • a random sample taken from WAT files of the May crawl

The remaining URLs (more than 2 billion) have already been included in one of the previous monthly crawl archives and have been stored in our URL database for a later re-fetch – if not marked as duplicates, classified as spam, etc. This huge “collection of bookmarks” dates back multiple years, even back to 2012 when we first received seed donations from Blekko. This month we started to remove old “bookmarks” from our URL database. In the future we’ll remember a URL for only 12 months after seen last as a seed or outlink. On the one hand, we hope to increase the dynamic of the crawls, on the other hand a smaller URL database will save resources.

To assist with exploring and using the dataset, we provide gzipped files which list all segments, WARC, WAT and WET files.
By simply adding either s3://commoncrawl/ or https://data.commoncrawl.org/ to each line, you end up with the S3 and HTTP paths respectively.

May 2018 Crawl Archive Now Available

The crawl archive for May 2018 is now available! The archive is located in the commoncrawl bucket at crawl-data/CC-MAIN-2018-22/. It contains 2.75 billion web pages and 215 TiB of uncompressed content, crawled between May 20th and 28th.

The May crawl contains 550 million new URLs, not contained in any crawl archive before. New URLs are “mined” by

  • extracting and sampling URLs from sitemaps, RSS and Atom feeds if provided by hosts visited in prior crawls. Hosts are selected from the highest-ranking 60 million domains of the Feb/Mar/Apr 2018 webgraph data set
  • a breadth-first side crawl within a maximum of 4 links (“hops”) away from the home pages of the top 40 million hosts or top 40 million domains of the webgraph dataset
  • a random sample taken from WAT files of the April crawl

To assist with exploring and using the dataset, we provide gzipped files which list all segments, WARC, WAT and WET files.
