WARNING
Rumors are circulating that recent changes to SL servers have created a massive problem with a 100% failure rate including complete loss of inventory.
The network connections that transfer you from one region to another are failing. TP’s to certain places consistently fail. Rumor is that if you manage to TP your inventory does not go with you.
