[still problems with log-in]

I've tried Google DNS + DTAG, also with no success. Also, attempted to use OpenDNS and OpenNIC -- same results. 

[still problems with log-in]

Same issue for me. DNS error messages all day yesterday and then today, very slow and unstable connection. Constant crashes and lag. Also based in Germany. 

[DNS could not resolve the host name?]

Same problem here, and also based in Germany. 

 

I can sign into SL now but only after an unusually slow sign in process, small glitches with display names when I am eventually logged in, etc.
