Directing the question correctly.
ASK US
The site is unreachable and you want to know whether our server is up A certificate at our end is invalid Errors appear in our logs AutoSSL is failing Resource limits are being reached You want to know what your DNS records should be You are unsure whether a problem is ours or the proxy's
ASK CLOUDFLARE
Their dashboard, features or billing A Cloudflare-specific feature not behaving as documented An incident on their network
WHAT TO DO BEFORE EITHER
Pause Cloudflare. If the problem disappears, it is configuration; if it persists, it is at our end.
That single test saves a great deal of time and is the first thing we will ask.
WHAT TO TELL US
That Cloudflare is in use. Many tickets are slowed because nobody mentioned it.
The error number, if Cloudflare produced one.
The SSL mode and whether records are proxied.
THE PRACTICAL REALITY
Most Cloudflare problems are two settings: the SSL mode and the proxy state on mail records.
Check those before opening anything.
