We have started a Common Crawl discussion list to enable discussions and encourage collaboration between the community of coders, hackers, data scientists, developers and organizations interested in working with open web crawl data. Please join our discussion mailing list to:
- Discuss challenges
- Share ideas for projects and products
- Look for collaborators and partners
- Offer advice and share methods
- Ask questions and get advice from others
- Show off cool stuff you build
- Keep up to date on the latest news from Common Crawl
The Common Crawl discussion list uses Google Groups and you can sign up here.
Erratum:
Content is truncated
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.
Erratum:
Nodes in Domain-Level Webgraphs Not Sorted and May Include Duplicates
The nodes in domain-level Web Graphs may not be properly sorted lexicographically by node label (reversed domain name). It's also possible that few nodes are duplicated, that is two nodes share the same label. For more details, see the Issue Report in the cc-webgraph repository.
The issue affects all domain-level Web Graphs until the issue has been fixed for the May, June/July, August 2022 Web Graph (cc-main-2022-may-jun-aug-domain) and the following Web Graph releases.
