As of approximately 5:00pm (PST) the www.dotnetnuke.com site was restarted, and so unavailable for approximately 30 seconds while the worker process was recycled.
The purpose of the restart was to pick up on a change in the mail server IP address, which was apparently not updated by clearing the Host Cache.
The DotNetNuke email server was previously hosted for us by our friends at Portal Web Hosting. We appreciate the services that they have donated to the DotNetNuke Project in service of our community. Our email services have now been moved to a dedicated email server in our own infrastructure sponsored by MaximumASP. Our email services are running on software provided by our parter, Merak Mail Server v8.2.4.
With the added flexibility of owning our own mail server, we look forward to increasing the efficiency and communication of our team and community through email, listserv, group scheduling and other available features.
