Massive DDoSes in the Chicago area are affecting entire ISPs, flooding their links to certain datacenters. These attacks aren't aimed at us, and aren't even aimed at the datacenters we use. But the size of these attacks are causing traffic jams on the big links providers use to connect to datacenters.
This causes 1 minute - 2 minute packet loss events for players on affected ISPs.
For the moment we suggest you either switch Chicago datacenter if these attacks affect your game, or play in a different region. CHI1 and CHI2 are in one datacenter, CHI3 and CHI4 are in another and CHI5 is in yet another one.
