| 07/15/2003 | During a routine firmware upgrade for network switches on Sunday night the 13th, we experienced an unexpected outage of the network backbone. The outage would have interrupted any web or network traffic between approximately 11:00pm and 3:00am. We regret any inconvenience this may have caused. |
| 05/27/2003 | Email sent to students who are not enrolled for summer classes was returned to the sender between 1:00 a.m. and 8:15 p.m. on May 24. This problem affected students not enrolled for summer classes and messages sent to username@truman.edu. Email sent to aliases was delivered properly.
This issue was caused by a problem in the automatic update of email alias files on the mail exchanger server. The problem has been resolved, and should not occur again. Any mail that was affected was returned to the sender as undeliverable. |

Database-driven websites such as the ITS website and the Trudex Searchable Index were unavailable during this time. Services were restored shortly after the problem was reported. Initial information indicates a network interface card failure. We continue to investigate to confirm the cause of the problem. |

The fiber optic cables connecting Barnett Hall to the campus network have been damaged and are non-functional. There is no network access in Barnett Hall at this time. The backup fiber optic cables also appear to have been damaged and are non-functional. We are working on restoring service and are investigating alternative methods for network services to Barnett Hall. |

| 03/12/2003 | Access to campus email will be disrupted this afternoon for approximately 15-20 minutes beginning at 4:00PM. This disruption will be due to a critical upgrade for the email system.

| 02/25/2003 | Internet access was down and local network services were severely disrupted by a denial of service attack. Services have now been restored and investigations are continuing. |
| 03/07/2003 | The problem appears to have been resolved. On Wednesday afternoon, March 5, MOREnet changed the QoS (quality of service) for our Internet connection. Since then our Internet access has been back to normal. _________________________________ We are experiencing an intermittent problem with slow Internet access. We are working with MOREnet on finding and fixing the problem. Analysis has not revealed any problem on our local network. The Internet performance problem began Tuesday morning (2-19), vanished Friday morning (2-21) before 8 AM but returned on Monday morning (2-24). This problem also seems to affect Library access to Lance. A new network monitor point was installed Tuesday morning (2-25) to provide better trace information. Several sniffer traces were sent to MOREnet for analysis. The traces show a Internet performance problem. A computer has been set up in a DMZ completely past all Truman network equipment, it connects directly to the MOREnet router. This computer is experiencing similar problems with Internet performance. |
| 02/11/2003 | The following announcement was sent to all Faculty and Staff regarding email changes: Email Announcement |
| 01/30/2003 | Some people experienced a loss of network connectivity in Ophelia Parrish due to a problem with network electronics located in an Ophelia Parrish wiring closet. The problem has been corrected. |
| 01/27/2003 | Campus Pipeline services have been restored. The outage was caused by problems with the iPlanet web server that runs Campus Pipeline. _________________________________ Campus Pipeline is currently unavailable. Campus Pipeline, Inc. is looking at the problem. |
| 01/29/2003 | Between 1:00PM and 9:00PM on Sunday, January 26, the Truman network experienced several intermittent outages - the cause of which is still being determined. |
| 01/28/2003 | The network outage from midnight Friday night until around 9:00am on Saturday morning (1/25/2003) was due to the new SQL worm that is infecting systems across the Internet. Most universities connected to MOREnet were affected by this outage. Even though all the critical servers on campus were patched for this type of worm - there were 2 PC's that were hit. These 2 systems caused local network access to be extremely slow. These machines have been disconnected from the network. All local services were restored by 9:10am.
The follow was received from MOREnet regarding the outages: A new worm known as the SQL Slammer Worm was discovered on January 24, 2003. This worm targets servers running Microsoft SQL and causes a denial of service and loss of network availability. In order to restore network availability, MOREnet has temporarily stopped routing all port 1434 udp traffic across the backbone. While this may cause some interruption of SQL use, many MOREnet networks were simply unavailable on the morning of Saturday, January 25, 2003 due to traffic from this worm. Normal routing will be restored as soon as the threat has abated.
Windows NT, Windows 2000, Windows XP running SQL
Any Internet device or user attacked or abused from a compromised machine. Significant reports of loss of network availability (both inside and outside MOREnet) have come to MOREnet’s attention.
