We have been given notice of core switch maintenance by our Upstream Provider.This maintenance will be performed on 04/13/2008 between 00:00 AM to 01:00 AM EDT.The expected loss of connectivity during the maintenance is less than 5 minutes.
Name servers of our IP provider are facing a big DDOS attack. This is causing problem with rDNS (PTR) quries of our mailservers causing SMTP/POP services to timeout. The provider is already on to the issue and we are also working on putting in some temporary workaround for the issue.
