Cougar News Staff

The UH System experienced a computer network outage Friday during which Internet users at all System universities had difficulty connecting to UH servers.

The problem affecting numerous outbound ports, which began around 10 a.m., was caused by a denial-of-service attack that originated from an on-campus high performance computing lab, Information Technology reported Friday.

"Denial of service is an Internet thing where some entity or person tries to flood traffic into the network connection, which denies usersi connections," Dennis Fouty, associate vice president for Central Computing & Telecommunication Services, said.

Normal Internet access was restored by 8:15 p.m. Friday, IT reported.
