Does anyone know why some of us cant connect to West coast servers?

Does anyone know why some of us cant connect to West coast servers?

The servers are being ddosed at the moment.

This would prevent some from getting on specific servers and others able to get on? Ive got 3 friends on us West sleepers and when i load it just stays a a black screen. f1 tab sais connection failure. but i can get on east coast servers with no issue

Same here with the PvE Server. Stays at black screen. Maybe a regional problem in the US?
Caus I could join a few EU Server without probs.
