Hey sorry I've also had a lot of radio silence from them. It all started when I couldn't update our team's Zero Tier user seats count back in July, and that is still ongoing. Cloudflare's core systems seem to be up (in Cloudflare terms, up is relative), but their admin backend seems to be having serious issues that I'm hoping they are working on. And or give up and crack open some kind of Solarwinds samanage or BMC footprints or heck even some bugzilla - something to get them unblocked more than they are now.
I don't have any contact info to help with.
