It's pretty fair to assume someone on a USA site, run by an American company, that is a major VC firm based in San Francisco, in an article talking about moving away from another USA company that is located all of 2 miles away from ycombinator, and speaking english should be able to put 2 and 2 together when dealing with contextual information.

If they can't they probably should move to an international focused site.

The author of the article is not from the US, and is talking about a Slovenian alternative to Cloudflare.

Either way, we are on the internet. Pretty international stuff.
