The issue is definitely on SE's end:



Note 220ish ping is normal for aussies :|

What isn't normal is the massive wall my connection hits on SE's internal servers and more than doubles to over 500+.

Seriously, no more its you not me, just out of benefit of doubt and to rule things out, please check your servers SE. Whatever 219.117.144.66 is, appears to be the culprit. I'm thinking its got something to do with mogstation/the authentication servers as that is also loading extremely slowly right now.
