Ok so all of us who are having the problem are on AT&T. It's not going to do you any good to bring this to AT&T's attention because the problem is happening downstream after it leaves their network. If you look at the MTR in my thread you see in the % column that it's zero percent packet loss until it hits Level 3's network in Boston. From there, Level 3 hands of to Lightstream which has four different devices on the trace.
I suspect this is the last mile provider that hands off to Rogean's floor space but I can't be sure. Because the problem is happening downstream it will likely require someone at the Boston end to either cease advertising their ASN to Lightstream (doesn't work if they're the last mile provider) or open a ticket with Lightstream to investigate what's going on at the handoff from Level 3 where the packet loss starts.
What would help is if as many people who are experiencing the problem as possible could post an MTR of at least 100 pings to login.eqemulator.net and post the text output here using this tool:
https://sourceforge.net/projects/winmtr/
It would also help if someone who is NOT experiencing the problem could post an MTR so we can see what that looks like.
