We have recently changed a few IP addresses, our web and eMail servers.  We made sure that the DNS system was appropriately updated to minimize the length of the interruption.
The one problem that we have had so far is that the nightly summary eMails are not being delivered to all members.  Specifically some of our members with @aol.com and @yahoo.com emails did not get emails this morning.  We are sorry for this inconvenience and are working to correct this problem.
