Today, Tuesday, some time after the restarts people started to see problems. There was no software rollout today, just a restart.
There is very high packet loss of everyone. Which is an indication it is on the Lab’s end of the network. Even Lindens were seeing the packet loss. While some of them work from home or remote offices, some work at the Lab. That is even more indication that it is not an ISP or remote problem.

You can see if you are getting bit by opening your Viewer Statistics panel (Ctrl-Shift-1). Look for Packet Loss. Mine was bouncing between 0 and 75%. Obviously that is going to cause a sluggish viewer and things are not going to work well. Chat log and groups are wacky too.
I suggest avoiding doing money transactions or rezzing No Copy items.
