CAn't log in...

I have the same problem.
I wrote Linden Labs more then one Email about the Login Problems and get only the automated Email back. I have wrote them also what I saw in my Network Analyzer and getting no answer back.
In my Analyzer I saw that my client is sending SYN packets and getting no ACK packets back, so this is definitely a Server Problem. I think the Server are overloaded.
With the 1.6.5 preview I can't also not login.
This is more then bad quality, is this still beta code ?
I wont recommend SL to my friends anymore, the probably will kill me if they have to login. Linden's whats wrong, please deliver answer.
Today I was wasting 2 hours to not get in SL...I really don't know for what I paying you money !

having same problem. e-mailed linden. only automated response.

I cant log in either. Have been trying for several hours. I cant imagine how I even want to waste this much time. Lindens need to adress this issue NOW, not on the next update. I was able to get in this morning and had no real problems. However, its seems to be a pattern for afternoon/evening entry. Does anyone else have this same issue?

Have been having major problems viewing streaming video also. Did not have this problem a week ago.
