I just now got in, I haven't been able to get in at all to any of the 4 servers (www, dharma, loki, ragtime) since, I think, yesterday afternoon, despite trying every few hours. Today, it worked although I didn't do anything different from normal.
I use CompuServe, and I kept getting the message "site not found ... are you sure you spelled the name correctly? etc."
My cookie seems OK.
