[L4D1] DDOS Attack to official servers
Somebody is DDOS-ing Left 4 Dead 1 official servers 24/7. Everytime somebody tries to play on any server, a DDOS attack is triggered within 30 seconds - 2 minutes. It occurs on Chile, Peru and US East servers. I have not tested more locations, i am from Argentina, I play on chile servers.
Host locally does not work always because of "No Steam Logon" bug which is from 2008 and has been never fixed.
I cannot do anything because I dont own Valve Left 4 Dead Dedicated Servers. Please, install an anti DDOS system or something. Hackers don't let us play. I have already reported this on Steam and they told me to post it here.
I can confirm that it also happens on the US West servers.
This issue seems to be fixed for now. I haven't noticed any new attacks since the latest update.
Closing per the last comment.
