I sent this to technical support but wanted to post here also - while logged into second life today, my firewall caught the following attempt:
"Blocked rat trojan horse (userserver.agni.lindenlab.com(66.150.244.151),2989)."
I have no idea what this is exactly but thought the lindens should be made aware of it, and also anyone out there without a firewall.... I can no longer log into second life either, don't know if the grid is down or if it's just me. 4:20pm EST.
