Pretty neat. Man, I love my internet connection. ~40ms to the nearest, and I live way out in the country. Thank you EU-funded projects!
There are a ton of European results in yours that do not appear in the post's site. Is that because those are colocated?
Yes. Some Google Cloud zones are in Google's own data centers and some are in third-party data centers. I vaguely remember them at some point also listing those third-party data centers somewhere, but I can't find it now and might be misremembering.
