Unfortunately... yes. They have Europe coming "really soon" when we were talking to them which we're excited about, but it's one location in the west coast of the US currently.
They said they use Cloudflare as well...
We do use Cloudflare, but a lot of the instance backups we store are multiple GBs - Cloudflare doesn't cache those. Not to mention uploads from regions like Singapore can be very slow all the way to the US.
It's not a deal-breaker for us, but we're very much looking forward to when they can support more regions.
