Update on Cyrus Migration22 Jun 06
All active email users have now been moved to the new Cyrus email system. The migration of inactive users (people who have not used our email system recently, but who still have accounts and stored mail) will be completed over the next few months. If you have not yet heard from us about your own move, don't worry -- you'll hear from us soon.In the past several weeks, as the system has grown into one of the largest Cyrus installations in the world, we have faced new performance issues which caused several episodes of delayed message delivery or access difficulties for some of you. These have been resolved quickly, and we continue to monitor performance and implement improvements. The nature of these problems is quite different from the performance issues that plagued the old mail system before the migration to Cyrus began. Then, the problems were a sign of an old system's inability to handle the demands placed on it. The problems we face now with Cyrus are simply growing pains, which are natural as we refine configurations to make optimal use of this flexible, modern mail system. Outside of these incidents the new system is running well. We continue to rely on a highly effective, system-wide spam and virus filtering system based on the MIMEDefang and SpamAssassin software. The system-wide filters block about 700,000 messages per day from entering the Columbia mail system -- and from ending up in your mailbox. (That's 700,000 out of the 1.6 million messages that arrive at Columbia on a typical weekday.) Individuals can use an online tool to set their personal spam "threshold" even lower, or to filter out messages from specific senders. What’s NextMigrating all the old mail to Cyrus is not the end of the process by any means. We continue to investigate, develop, and deploy behind-the-scenes system improvements and tools to make it easier for you to manage your email. Currently we're working on web-based tools to allow you to recover your own deleted messages, to see space usage on a folder-by-folder basis, and to control ACLs (access control lists) for shared mailboxes. More information will be forthcoming when these are ready for you to try out.Jill Williams Client Services |
