The Relay Service is now back online and running against the July CTP of the .NET Framework 3.0 . There's also an updated Relay SDK to go with it. Just follow the instructions on the Getting Started page to get going. And as always, send us your questions...

Just a quick note to let you know that we're going to be taking down the Relay and STS for a few hours towards the end of this week (tentatively Friday) to move to the July CTP. - Dennis on behalf of the Relay & STS teams.
