xMail Slowness - Resolution Underway Jan. 19, 2012 - We have begun a mitigation process for the xMail slowness by moving some people off to other servers. The process will continue over the weekend; the slowness issues should resolve as the migration continues. A permanent resolution will be forthcoming in the next few months as we migrate xMail to a new Exchange environment. Recap of event: Over the past few days, users of xMail, the University's central Exchange-based email and calendaring service, have been experiencing sporadic issues with slow or delayed response times. This is because our Exchange infrastructure is nearing its maximum capacity in terms of memory usage, causing occasional slow response times during peak usage. We are mitigating this by distributing users across more servers. |

xMail Slowness Jan. 18, 2012 - Over the past few days, users of xMail, the University's central Exchange-based email and calendaring service, have been experiencing sporadic issues with slow or delayed response times. This is because our Exchange infrastructure is nearing its maximum capacity in terms of memory usage, causing occasional slow response times during peak usage. ITS is working on a solution which will be implemented over Jan. 18-19; we do not expect any disruption for the general xMail user community. |

RESOLVED: VoIP Call Center Issue Affecting IT Services Contacts Dec. 27, 2011 - At approximately 8:30 a.m. an issue was detected with the portion of the VoIP phone system which provides call center functionality. The only client utilizing the VoIP call center function which was impacted is IT Services. As a result, attempts to reach IT Services via 2-5800, 2-9100, 4-8324 or 2-1234, and reach a live contact, were queued on hold until 9:10 a.m. Service was restored at approximately 9:10 a.m. and calls are now being answered normally. ITS will investigate the cause of call center issue to see how it can be prevented in the future. |

RESOLVED - Authentication Issues Dec. 14, 2011 - As of 9:20 a.m., login problems to ITS services have been resolved. Recap of event: At approximately 9 a.m., the primary campus authentication servers (LDAP) ran out of memory following a software upgrade. As a result, people encountered problems logging on to servers depending on this authentication, including wireless, cMail, Chalk, VPN, and several administrative systems (UCTime, GEMS, etc.), among others. The issue was resolved at approximately 9:20 a.m. by reverting to the old software version and restarting the services. ITS will investigate the cause of the memory issue before re-attempting the upgrade at a later date. |

RESOLVED: Wireless on North Side of Campus Dec. 1, 2011 - As of approximately 2:40 a.m. this morning, wireless on campus is again functioning normally. Recap of event: At approximately 9:30 a.m. Wednesday, Nov. 30, a configuration issue began causing sporadic network loops between two wireless gateways. As a result, users of the non-secure 'uchicago' network began seeing sporadic network disruptions, as the gateways reset themselves to break the loop. The issue was resolved at approximately 2:40 a.m. Dec. 1 by reconfiguring the affected network links. The secure wireless networks (uchicago-secure and eduroam) were not affected by this problem. |

Wireless Issues on North Side of Campus Nov. 30, 2011 - At approximately 9:30 a.m., some of the appliances serving the non-secure 'uchicago' wireless network became unstable. As a result, people using the 'uchicago' wireless network on the north side of campus (between 58th St. and 55th St.) have been having sporadic problems connecting to the network. The secure wireless networks (uchicago-secure and eduroam) are not affected; see http://answers.uchicago.edu/search.php?q=wireless,configuration for instructions on manually connecting to the secure network if you are having issues with the non-secure network. IT Services staff have identified the root cause of the problem, and have scheduled a fix after 1 a.m. tonight to avoid a larger disruption. MeetingIDs and GNetIDs cannot connect to the secure wireless network and will therefore have connection problems on the north side of campus until the problem is resolved. |

RESOLVED: Email Bouncing Issues Nov. 16, 2011 - As of approximately 9:15 p.m., email and authentication services are again operating normally. IT Services staff will be contacting individuals who had email returned, so they can contact their correspondents and ask for a re-send. Recap of event: At approximately 2 p.m., an issue on the University's central authentication servers (LDAP) began delaying updates for password changes, email forwarding changes, and new account creation. At approximately 8:20 p.m., the problem expanded to existing email forwarding. As a result, roughly 4% of our email traffic (~550 messages) were incorrectly returned to the original senders. Normal operations were restored by 9:15 p.m. IT Services staff will be contacting people whose email bounced, and will also be investigating the cause of the issue to see how it can be prevented in the future. |

Email bouncing issues Nov. 16, 2011 - Earlier this afternoon, an issue on the University's central authentication servers (LDAP) began delaying updates for password changes, email forwarding changes, and new account creation. At approximately 8:20 p.m., the problem expanded to existing email forwarding; this is causing email to some users to be returned to the original senders. IT Services staff are currently working to resolve the problem and identify the affected addresses. |

RESTORED: Wireless Authentication Issue Nov. 15, 2011 - At approximately 12:30 p.m., a memory issue on the wireless authentication server began causing connection problems for users across campus. IT Services staff were alerted to the problem and fixed the issue by approximately 1:05 p.m. If you are still having problems connecting, try restarting your machine, or call the Service Desk at 2-5800 (773-702-5800). IT Services staff will be re-tuning the authentication server to help prevent this error in the future. |

RESTORED: cMail/Webmail Nov. 1, 2011 - At approximately 6:40 p.m., webmail.uchicago.edu, the web front end to cMail, stopped responding to requests. The problem was fixed by restarting the webmail servers; service was fully restored by 6:50 p.m. IT Services staff will be working with the vendor to determine how this issue can be prevented in the future. |
