So this just recently happened today. This afternoon I was unable to do my WaniKani reviews and check my preferred online dictionary. Surprisingly, everything worked when using a VPN. So to anyone who is in the same boat as me, get a VPN as PLDT is still investigating the issue.
I’ve switched from Google’s to PLDT’s and then to Open DNS but it’s still the same. Also flushed the DNS and checked my hosts file. It’s not even an isolated issue with my computer as my smarphone can’t sync the Flaming Durtles app through wifi.
