Issue: Wednesday, October 12, 2011 at approximately 12:05 p.m., OIT received notification that Internet response times were slow in multiple buildings on campus. The problem was resolved at approximately 8:00 p.m.
Background: The CU campus uses the Front Range Gigapop (FRGP) as our Primary Internet Service Providers. The FRGP employs specialized on-site servers designed to optimize content and media delivery for web site response allowing for rapid content load times. This service is hosted by Akamai Technologies.
Cause: Upon investigation, it was determined that the Akamai servers located at the FRGP were experiencing very high traffic loads. This caused delays in the cached information to be uploaded into various web sites being accessed by campus users and resulted in reports of slow Internet response times.
Solution: Upon identifying the high traffic loads on the Akamai servers the FRGP issued notification and began to monitor the traffic for any anomalies or denial of service attacks. No issues were found with the traffic types and it was determined the units were under high demand based on normal Internet traffic. The demand slowed through the evening hours and response times returned to normal at 8:00 .pm.
What can be done to prevent this again?: The FRGP is working with Akamai Technologies to increase the bandwidth between the FRGP and the locally supported Akamai servers to alleviate high traffic load requirements in the future.
