I unplugged my fiber gateway overnight. Unfortunately, I'm still having the same issue this morning - need to hop onto a VPN to access rivals.
I ran some analysis against rivals.com yesterday (directly, not via VPN). Nothing leapt out at me as being unusual or amiss. Couple open ports (80/443), ton of filtered ports, couple closed ports (bnetgame/rtmp). Nothing atypical.
Which is more or less what I expected given most people seem to be able to access it okay and it's a relative few of us reporting issues.
One unknown server involved in the routing. Final 3 servers (unknown/ae-70.core1.nya.edgecastcdn.net/rivals.com @152.199.0.82).
@Richard Schnyderite, I'm in the Edison/Woodbridge/Piscataway region. Some of the others are from other regions, including out of state.
