Was playing Diablo with my brother in Australia. My connection dropped out, his did not. ALL connection to Blizzard server dropped out for me, while he who was connecting through a different ISP did not. I tried connecting through my VPN (after computer and modem reset failed to fix) and the first connection on an Australian server failed to connect also.
Connecting through my VPN to a US server though allows me to post here, and even log onto game servers (with significant lag). Hope you can help because it’s unplayable as is.
