Recent Kerberos and Authentication Problems
Recently, there have been periods when authentication to the SCS Kerberos servers has been extremely slow, causing some applications to time out when authenticating.

Many of you will see this as an apparent issue with access to your email. Please know that the email servers are performing well and your data is safe, even if your access is intermittent due to these incidents.

We are aware that these incidents are causing critical service outages, and fixing this problem is our highest priority. We are currently in the process of implementing procedural and system-based solutions.

Please contact the SCS Help Desk at x8-4231 or send mail to help@cs.cmu.edu with any questions or concerns.
