Run through the steps in http://blog.nalates.net/2011/10/26/troubleshoot-your-sl-connection/ 

There is a section on upgrading your DNS service.

Your viewer and SL's servers have temporarily lost the ability to talk to each other. Unless there's a problem with the servers (Always check http://status.secondlifegrid.net/ first), it's probably something on your end. So....

(1) Try shutting off your computer, unplugging the router and modem for a couple of minutes, and then plugging them back in and restarting. That simple step may clear up everything

(2) Add Google's free public DNS servers to whatever your ISP assigns you as a default. Here's how >>> https://developers.google.com/speed/public-dns/docs/using

(3) If things are STILL messed up, contact your ISP. Maybe they are working on their Internet connections.
