Host- and Domain-Level Web Graphs August, September, and October 2025

Note: this post has been marked as obsolete.
We are pleased to announce a new release of host-level and domain-level web graphs based on the crawls of August, September, and October 2025, consisting of of 468.4 million nodes and 8.0 billion edges at the host level, and 97.7 million nodes and 6.0 billion edges at the domain level.

We are pleased to announce a new release of host-level and domain-level web graphs based on the crawls of August, September, and October 2025. The crawls used to generate the graphs were CC-MAIN-2025-33, CC-MAIN-2025-38, and CC-MAIN-2025-43. Additional information about the data formats, the processing pipeline, our objectives, and credits can be found in the announcements of prior Web Graph Releases. You may also visit the projects cc-webgraphand cc-pyspark which include all scripts and tools required to construct the graphs. Instructions to explore the graphs in the webgraph format are given in our collection of Web Graph Notebooks. You may also wish to explore our Web Graph Statistics page for more information on ranking.

Host-level Graph

The host-level graph consists of 468.4 million nodes and 8.0 billion edges.

There are 410.4 million dangling nodes (87.62%) and the largest strongly connected component contains 36.9 million (7.89%) nodes. Dangling nodes stem from:

  • Hosts that have not been crawled, yet are pointed to from a link on a crawled page
  • Hosts without any links pointing to a different host name
  • Hosts which did only return an error page (eg. HTTP 404).

Host names in the graph are in reverse domain name notation and a leading www. is stripped: www.subdomain.example.com becomes com.example.subdomain.

You can download the graph and the ranks of all 468.4 million hosts from AWS S3 on the path s3://commoncrawl/projects/hyperlinkgraph/cc-main-2025-aug-sep-oct/host/ (this requires an account on AWS). Alternatively, you can use https://data.commoncrawl.org/projects/hyperlinkgraph/cc-main-2025-aug-sep-oct/host/ as prefix to access the files from everywhere.

Please note that the text representation of the host-level graph is shipped in 48 gzip-compressed files listed in two path listings - one for the nodes (vertices), one for the edges (arcs). First, download the paths listing and decompress it using gzip -d or gunzip. By adding the prefix s3://commoncrawl/ or https://data.commoncrawl.org/ to each line in the path listing you get the list of URLs to download the entire graph.

Domain-level Graph

The domain graph is built by aggregating the host graph on the level of pay-level domains (PLDs) based on the public suffix list maintained on publicsuffix.org. Version (commit) 0673151 of the public suffix list was used (commit date 2025-10-01T18:52:03Z).

The domain-level graph has 97.7 million nodes and 6.0 billion edges. 53.1% or 51.9 million nodes are dangling nodes, the largest strongly connected component covers 31.7 million or 32.49% of the nodes.

All files related to the domain graph are available on AWS S3 under s3://commoncrawl/projects/hyperlinkgraph/cc-main-2025-aug-sep-oct/domain/ or on https://data.commoncrawl.org/projects/hyperlinkgraph/cc-main-2025-aug-sep-oct/domain/.

Erratum: 

Content is truncated

Originally reported by:

Some archived content is truncated due to fetch size limits imposed during crawling. This is necessary to handle infinite or exceptionally large data streams (e.g., radio streams). Prior to March 2025 (CC-MAIN-2025-13), the truncation threshold was 1 MiB. From the March 2025 crawl onwards, this limit has been increased to 5 MiB.

For more details, see our truncation analysis notebook.
