Today (6/10/2010) the Windows Azure AppFabric has updated the IP ranges on which the AppFabric nodes are hosted. If your firewall restricts outbound traffic, you will need to perform the additional step of opening your outbound TCP ports and IP addresses for these nodes. Please see the 1/28/2010 “Additional Data Centers for Windows Azure AppFabric” for full list of IP ranges, which was updated today to include changes shown below.

Updates made today are shown below:
