I’d believe half of all traffic to non-video hosts, however. We provide a lot of free content and it’s staggering how many bad robots there are - not actual malice, just what you’d expect from lousy programmers who don’t get the bill. Things like the same IP / User-Agent downloading the same file thousands of times just in case it changed in the last 5 seconds or crawling millions of permutations of search parameters rather than using the site maps. Many week that’s half of the total traffic, many tens of terabytes of HTML & JSON.
