Root Cause / Continuous Improvement:

The issue experienced on Friday was the result of a problem with one of our Internet Service Providers.  At approximately 3 pm on Friday, the Help Desk along with Networking began to investigate issues with Internet connectivity as we received reports from around campus.  After determining that the issue was likely not with any PLU equipment, we proceeded to contact the ISP which handled the connections being affected.  During out communication with the ISP, a stop-gap was put in place to resolve the majority of issues with connectivity, and we declared the issue resolved at that time.

For any possible future events, we will do our best to improve our response speed to network connectivity issues.  The Help Desk was grateful for all callers who assisted by providing us with the requested information.  For future network issues, we will continue to use the PLUHelpDesk Twitter account as a primary means of communication.  (As normal network communication may not be possible).  We strongly advise that users subscribe to our Twitter feed.  Subscribing is simple and does not require a Twitter account.  This account is for informational posts only and will not post any non-status related updates.

Additional Info:  Our ISP informed us that the issue was the result of a configuration issue which resulted in what is known as a broadcast storm (wikipedia).  This resulted in a 55 minute outage.  The ISP is working to update and improve the broadcast storm detection tools and to investigate why the error was not reported quicker.
