Timestamping a Giant Record of the Web

Automated excerpt

It happens to be the number of web page snapshots captured by the Common Crawl project over the past 18 years. Common Crawl's hundreds of billions of snapshots save web pages precisely as they existed over the years, totalling more than 10 petabytes of snapshot data. Fortunately, Common Crawl had already hashed all web page snapshots and collected the hashes in blocks of up to 3000 index entries.
