Unstable DNS in Brazil (again)

https://cdn.jesteriruka.dev/vehicles/panto.png ^ R2 Bucket, timeout every single time. When the same URL is requested through OVH (United States), the requested file is downloaded just fine. For some reason, other projects (with Pro plan) don't seem to be affected. My ISP is Vivo (Telefonica Brasil), a lot of my customers are talking about this, there is also a considerable amount of reports on https://downdetector.com.br/fora-do-ar/cloudflare/

For context: storage.hydrus.gg is also a R2 bucket, but it works. Seems to be solved now, at least for my ISP.

Yes, I also forgot to say this, but jesteriruka.dev has ipv6 disabled. But wasn't only my computer, I provide some sort of SaaS for gta scripting, and a lot of customers had the same connectivity issue with my domain. Maybe that is the reason why other zones didn't had the same issue

a good reason to enable IPv6 perhaps, could have been an ISP-wide issue. If it happens again, traceroutes (tracert on windows) are helpful

I did one but didn't sent it.

Unfortunately I'm not sure if I can enable ipv6 without major issues, there is a lot of tokens that are assigned to ipv4, which will break the authentication, maybe is best to just leave this specific area to another A record without cloudflare proxy.

hmm, that looks like it was from when it was working since you reached the ip in the end

JesterIrukaOP•3d ago

I did before the successful ping, but probably took long enough to just work.
