Host- and Domain-Level Web Graphs March, April, and May 2026

We are pleased to announce a new release of host-level and domain-level web graphs based on the crawls of March, April, and May 2026. The graphs consist of 262.4 million nodes and 8.1 billion edges at the host level, and 118.8 million nodes and 4.3 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 March, April, and May 2026. The crawls used to generate the graphs were CC-MAIN-2026-12, CC-MAIN-2026-17, and CC-MAIN-2026-21. 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-webgraph and 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 262.4 million nodes and 8.1 billion edges.

There are 198.2 million dangling nodes (75.56%) and the largest strongly connected component contains 36.6 million (13.96%) 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 such that: www.example.com becomes com.example.www.

You can download the graph and the ranks of all 262.4 million hosts from AWS S3 on the path s3://commoncrawl/projects/hyperlinkgraph/cc-main-2026-mar-apr-may/host/ (this requires an account on AWS). Alternatively, you can use https://data.commoncrawl.org/projects/hyperlinkgraph/cc-main-2026-mar-apr-may/host/ as prefix to access the files from everywhere.

Please note that the text representation of the host-level graph is shipped in 240 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) 8b4345f of the public suffix list was used (commit date 2026-05-01T02:51:16Z).

The domain-level graph has 118.8 million nodes and 4.3 billion edges. 63.0% or 74.8 million nodes are dangling nodes, the largest strongly connected component covers 30.2 million or 25.46% of the nodes.

All files related to the domain graph are available on AWS S3 under s3://commoncrawl/projects/hyperlinkgraph/cc-main-2026-mar-apr-may/domain/ or on https://data.commoncrawl.org/projects/hyperlinkgraph/cc-main-2026-mar-apr-may/domain/.

Erratum: 

Content is truncated

More details
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.
