We have been seeing intermittent connection failures between Cloudflare and our origin (an AWS load balancer) for the last few days. I opened a support ticket (#2368471) at the weekend, and the next day Cloudflare replied:
we found an issue at the colo in Frankfurt, and our team have fixed the issue and this should not happen again
This seems to indicate a fault on the Cloudflare side, and I am grateful for the response. But the issue is not fixed, and the ticket hasn’t had a response in over 24 hours. Meanwhile ~50% of requests to the website are failing with a 520 error.
Is there a way to escalate a support ticket (I’d have thought it would have been escalated for future replies when CF identified a fault on their side)? Does anyone have any suggestions on how we could debug this ourselves?
