Cloudflare and recent downtime due maintenance

[blacknight.the89]

Shouldn't cloudflare show the cached version of my website while you were doing the maintenance, installing litespeed and other things instead of a 502 error page ?

Cloudflare will only show cacheable/static elements, and most pages are not cacheable unless you modify the cache-control or expires headers. See Section 14 of RFC 2616 for details on cache and proxy behavior using the cache-control and expires HTTP header fields.

Oh ok, I changed a bit the headers, now, i'll wait and see what happens! Many thanks!
