| 02/16/2004 | MOREnet technicians will be upgrading the MOREnet backbone during the maintenance window on Sunday, February 15, 2004. The upgrade, occurring between midnight and 6 a.m., will quadruple the backbone's capacity without increasing costs.
Each hub location (Kansas City, Columbia, St. Louis, Jefferson City and Springfield) will be upgraded separately. As technicians switch a location from the old OC3 circuit to the new OC12 circuit, customers may experience brief, intermitant outages. |
| 02/11/2004 | At ~ 1:40 this afternoon we began experiencing slow Internet access. We are investigating the cause of the problem. ** 2 PM Update ** It's another zero length packet flood, but on a different set of ports than the mydoom virus denial of service flood uses. ** The source of the network disruption has been identified and disabled. Internet access has returned to normal |
| 02/13/2004 | Home computers infected with the MyDoom virus and its variants are disrupting Truman dial-up services. We are working on a way to address the problem. |
| 02/10/2004 | The problem that caused the slow Internet access late yesterday afternoon and early evening has been addressed. The temporary restrictions on high TCP/IP ports that was activated last night has been removed. |
| 02/09/2004 | Internet access slowed dramatically around 4:30 this afternoon. MoreNet was been notified and ITS is investigating. ** Updated @ 5:25 PM ** The problem is being caused by a flood of zero length network packets both into and out of Truman. The disruptive machines are being disconnected from the network. ** Update @ 6:55 PM ** The flood continues on a range of machines into and out of Truman. The zero length packets are all in the high TCP/UDP port numbers. Access to high numbered IP ports has been temporarily restricted to only Truman servers. |

| 02/04/2004 | Due to the recent problems with the front-end email server, ITS Network Services will be doing some unscheduled configuration changes this evening at approximately 5:30pm. The recent problems have been caused by an unexpected reaction to a variant of the MyDoom virus. The outage should be less than 15 minutes. UPDATE: The fix has been applied and service restored as of 6:00pm |

| 01/30/2004 | The terminal server (dial-up access) was rebooted today at approximately 11:10, Thursday 1/29, due to system problems caused by a connection from a Blaster-worm infected computer. Steps are being taken to isolate the infected computer and prevent continued problems. |
| 01/27/2004 | In order to clear an application error, the administrative web server Argon was rebooted at approximately 5:30. All services were restored within 5 minutes. |
| 01/28/2004 | Campus Pipeline is currently unavailable. IT Services and SCT/Campus Pipeline support are investigating the cause of the problem. More information will be posted as it is available.
UPDATE: Campus Pipeline is now back online. After the outage this morning, we have installed a service pack on the Pipeline webserver, which will hopefully fix the problem. |
| 01/30/2004 | On Jan 26, a new computer virus was found. The virus (W32/Mydoom@MM) is a mass-mailing worm and McAfee has classified the virus 'High-Outbreak'. Refer to http://vil.nai.com/vil/content/v_100983.htm for more information. McAfee released a new DAT file 4319 last night and with ePO managing the campus systems, 1400 systems have already been updated. The front end email routing server is protecting the campus from any incoming emails with the latest virus. You can verify that your system is up to date by following these steps: right-click on the 'V' shield icon in the bottom right corner of your screen and select 'About VirusScan Enterprise..', the latest 'Virus Definitions' should be 4319 (they are usually updated weekly) and then click 'OK'. If the definition is not 4319, right-click the 'V' shield icon and select 'Update Now'. |
| 01/26/2004 | Internet access suddenly slowed down at 3 PM today. It has largely returned to normal as of 3:45 PM. We have a ticket open with MOREnet on this incident. The preliminary investigation showed a very large inbound data stream was being directed at our network from an external location. We are continuing to investigate. |
| 01/21/2004 | There was a problem this afternoon with slow Internet access from 12:45 - 2 PM. The problem was caused by several machines on campus generating millions of UDP packets. The problem machines have been disconnected from the campus network. |
| 01/16/2004 | There was a short email sending problem this morning with sendmail. It was restarted at 7:40 AM and email sending is back up. We're investigating and working with the vendor to identify the cause of the sendmail failure. |
| 01/15/2004 | There was a brief email problem this morning. The problem was traced down and corrective action taken by ~ 8:40 AM. We are still investigating what was responsible for causing this mornings email problem. |
| 01/14/2004 | All email queues have been processed. All email systems are now working normally. There are no known email problems at this time. |
| 01/14/2004 | Due to the large volume of email that was queued during the recent Campus Pipeline student email problem email access may be slow for awhile. There are currently over 27,000 email messages queued on the email router. The email router is delivering messages and the queue is going down but it will take some time to completely catch up. We are continuing to monitor the email systems to ensure they are working properly. |
| 01/14/2004 | ** Updated 8:30 AM ** Campus Pipeline services have been restored. Student email is back up. The Campus Pipeline server crashed early Tuesday morning. We have been working with the vendor non-stop since then to correct the problem. The cause of the failure is still being investigated but it was software based. There were no hardware problems with the server. |

An update will be posted as soon as service is available. -- Update 2:15pm 01/02/04 -- Truman Dial-up service has been restored. The problem was due to a service failure on the server which handles authentication for the dial-up system. |
