Hi. I am sorry about this issue. Can you email dane@cloudflare.com, and it will get resolved? I am also working on more systematic fixes for when customers get into this situation.

With a recent announcement we are addressing this by dynamically moving the code to be close to the data when appropriate - https://blog.cloudflare.com/announcing-workers-smart-placeme...

All of Cloudflare services ship with IPv6 day 1. IPv6 not an issue as we have enough IPv6 for each machine to have own IPs.

That is correct. We run baremetal and all process run on all boxes. The one exception is we put our remote browsing product in gvisor which does use containers.
