Hi! We’ve been having trouble connecting to any *.roblox.com address from Google Compute Engine instances. The problem occurs even across various regions and IP addresses. This does not seem to be the case with AWS EC2 instances on any region, however, so we’re assuming it’s not some sort of massive block on cloud hosts and that there might be something stranger going on.

Is this a ROBLOX or Google-side block, or is there a different problem going on?
