CSL IMAP Outages Sunday, Oct. 26th

The CSL IMAP server suffered a power supply failure early Sunday morning which caused an unexpected mail service outage. As soon as the CSL was aware of the problem, staff were on site and were working to bring the server up - IMAP returned to service by noon.

Following this outage, the server developed a file system error Sunday night between 6-7pm that created another service outage and necessitated further downtime due to the size of the affected system. Lab staff were again on site and working on its return to service until it was fixed around 1am.

The server has been up since and no further issues have been reported.

The CSL ordered replacement hardware for this server last Thursday and expects it to arrive soon. This hardware should improve the reliability and performance of the mail server going forward.

We apologize for the inconvenience and thank you for your patience. Please continue to send reports about service problems or oddities to lab@cs.wisc.edu as they are greatly beneficial in helping us debug these issues.
