QWEEDDYZ: Not for the first time. Sometimes it took more time for Blizz to fix it (laziness). Diablo is coop RPG, it is better to find someone on some forums or GameRanfger. For Wc2 it is better at least alternatively add gateways for war2ru server as backup one (nowadays it is more popular than official one, for real, im not advertise it - Blizz and\or GOG really almost kill official Bnet, including by that few times in a year long time servers down).
If you still want some lobbies for D1 it is indeed more stable way to have DevilutionX installed. At least as backup. There is a chance that this time (about 10th for that last 3 years) it wont go back online, so in some time in the future DevilutionX become only one way to play online. Sometimes that will happen.
I am hosting gateway for Diablo I, It should also allow War2 players to connect as well. There is also way to play on it over Radmin VPN to bypass 6112 UDP port for hosting. If anyone wish to play War2 and have issue contact me freely im hosting it anyway so letting other players in will not be an issue.
