I had this problem a few weeks ago, and it went away, but now it's back.

The thing is, the connection issue didn't even initially disconnect me from FFXI. I woke up and was still logged in. I was, however, unable to view who was in my linkshell or search for people. When I tried to zone, it timed out and I was disconnected.

I'm now unable to connect to PlayOnline at all, getting either a POL-1160 or POL-0011 each attempt.

Seems pretty obvious the issue is with the lobby server and whatever server handles zone transfers and searches (perhaps the same one?)...

Currently using Comcast in the Boston, MA area.
