@vincejv I suspect there may be an routing problem with Globe Telecom Philippines to certain parts of the Internet. This is not something we can address.

The IPs are those of hwcdn.net and tlb.hwcdn.net (StackPath Highwinds) which is our CDN provider. Can you confirm that the issue also happens via curl on the command-line, and that it affects all three of our main CDN domains?

$ time curl -I 'http://code.jquery.com/color/jquery.color.svg-names-2.0.0.js'

And for example these unrelated websites that also happen to be Highwinds customers?

@Krinkle would that be the case even if my MTR shows it can route to CDN without any issues? MTR on my end seems like it can reach jQuery's CDN, tried both TCP, UDP and ICMP probes, no issues with MTR.

From talking with Vince in our Matrix channel, I believe this was likely the result of our CDN inadvertently blocking incoming requests from known Tor relays.

I'll raise this more generally with our (next) CDN provider, but for now this particular issue was solved.
