Email Offline At the Home of Sendmail 179
BobJacobsen writes "The UC Berkeley email system has been either offline, or only providing limited access, for more than a week. How can the place where sendmail originated fall so far? The campus CIO gave an internal seminar (video, slides) where he discussed the incident, the response, and some of the history. Briefly, the growth of email clients was going to overwhelm the system eventually, but the crisis was advanced when a disk failure required a restart after some time offline. Not discussed is the long series of failures to identify and implement the replacement system (1, 2, 3, 4). Like the New York City Dept. of Education problem discussed yesterday, this is a failure of planning and management being discussed as a problem with (inflexible) technology. How can IT people solve things like this?"

Capacity planning is supposed to account for reduced capacity due to component failures, system outages, and temporary demand spikes due to restart events.

Also, email is used for a lot of very important stuff like sending reports, design files, etc. Having someone on campus that can fix problems is quite valuable. Your campus email will never be "accidentally" seized, locked out, etc. like people have experienced with google and yahoo. Because the campus maintains backups (or at least, they should), you data will never be suddenly gone with no chance for recovery like people have experienced with google and yahoo.
