How many 525 errors am I getting?

A user has reported that our site was down and sent us a screenshot of the Cloudflare 525 error page.

We’re not seeing this error ourselves. How can I tell how frequently this is occurring? If it’s a 1 in a million error I’m not really worried about it, but if it’s happening to >1% of requests I’d want to investigate further.

In this community tip, there is info on if the problem is happening intermittently.

There is a feature request in for what you suggested that you can vote on to ask for more info about how frequently this kind of error occurs etc.
