Tomorrow at 9am US Eastern, IU will be changing the IP address of open-mpi.org (and all of its associated services: email, web, etc.).
They're hoping it causes no downtime -- there should be proxies in place to relay traffic from the old IP addresses for the next week or two, so that no one should notice anything different while the DNS change is propagating.
svn.open-mpi.org will not be affected.
