I’m pretty familiar with DNS in general and CF in particular (being active user for several years), having no major issues until yesterday.
I’m on a Free Plan simple because the reliable DNS service is my only requirement (even CF proxy isn’t needed). But starting from 2023-12-04 i’ve started to get a lot of sudden unexpected errors trying to reach various services on my domain hosted with CF (both register and DNS service).
When I trying to debug the issue using host utility it shows something weird, like a sporadic timeouts from my LAN DNS resolver. But when I point host to exact CF server — it gives me a proper reply instantly!
So at first I thought it’s something with my LAN resolver.
But then I also start receiving similar sporadic ERR_DNS_NAME_NOT_FOUND on my mobile internet and my monitoring system (configured in other cloud) started to complain about same RESOLVE_ERROR.
I haven’t changed any settings or DNS records for a while, don’t even know what may cause this. Any advice?
