Can't load GitHub

[MarkJFine]

I did a traceroute to github.com and several other west coast sites in NoCal and Washington State and it seems it's a Level3/CenturyLink routing/backbone handoff problem.

I have not seen problems when I ping github dot com or tracert github dot com (via hughesnet), it always responds.

[MarkJFine]

I'm not. Mine's getting locked up somewhere 8 hops past HughesNet.

Pinging is fine, but the response is intermittently delayed and really not representative of what you need for a contiguous stream of data.

What I got as results. I don't know how to interpret them though.

[MarkJFine]

That's not bad. Mine goes from Level3 to zayo in LA and dies somewhere in there.

When I'm on hughesnet and ask a search engine "What's my IP address" it gives me a 184.xx.xx.xx number (dynamically assigned, may be different on different days).

That's same number that the web page on github-debug dot com retrieves in its tests.

It is the same number the github-debug dot com diagnostic is trying to ping when it reports "Destination net unreachable".

If I try to ping the same number, I also get "Destination net unreachable".

That "184.xx.xx.xx" number does not appear in any tracert that I've run.

[MarkJFine]

Interesting. That's actually your public IPv4. They won't be able to get to it because you're behind a double-NAT. So if they've suddenly started using that technique to verify faked IPs it's not going to get very far. Come to think of it, it might not work for people behind VPNs, either.

[MarkJFine]

Ok. So this is getting weird.

I went to https://140.82.113.3, bypassing the DNS going direct to their IP. FF told me it there was a domain error with the certificate (and rightfully so). I bipassed that and was redirected to https://github.com. The page displayed normally. Cool...

Did a shift-refresh to make sure it wasn't a cached version, and it timed out.

So it's definitely not IP validation because I wouldn't have gotten thru. There's something intermittently clogging the warp engines somewhere in the path and someone needs to play Spock.

Speaking of intermittent (and sllloooooow), I let it go and got in again:
