VALDOSTA — A faulty update to some Microsoft software has caused a widespread worldwide outage of computer systems, and not even Valdosta has escaped totally unharmed.

The update involved Microsoft Windows and is not believed to be connected to security or terrorist concerns, said CrowdStrike, the company behind the update.

Airlines were among the most high-profile businesses hit by the tech trouble. Thousands of flights from many carriers were grounded worldwide.

Of the two Delta flights scheduled for Friday from Valdosta to Atlanta, the 6:10 a.m. flight was cancelled and the 3:19 p.m. flight had been delayed for an hour and a half as of 11 a.m. Friday, according to Delta’s flight schedules website.

One of the two Delta flights from Atlanta to Valdosta Friday, the 1:33 p.m. departure, had been delayed as of 11:20 a.m. A second flight at 8 p.m. had not been impacted at that point. Delta is the only commercial passenger service operating out of Valdosta Regional Airport.

Operations at the airport itself had not been impacted as of noon Friday, said Airport Manager Chuck Miller.

Worldwide, some law enforcement agencies were reporting difficulties with the tech outage. The Lowndes County Sheriff’s Office had not suffered any problems, said Sheriff Ashley Paulk.

The Georgia State Patrol’s Atlanta office refused to comment on its tech situation, citing security concerns.

The Georgia Bureau of Investigation reported in a statement that its Georgia Crime Information Center — a clearinghouse for crime data for the use of law enforcement — has encountered difficulties with multiple systems.

“The GBI IT team is working with the state technology group to find a resolution,” the statement said.

911 call centers from Alaska to New York have reported being slowed up or even taken down as a result of the software problems.

The E911 center in Lowndes County, which also serves Echols County, has not been affected, said Tonya Davis, E911 service director.

Some universities were reporting difficulties Friday; Texas A&M University canceled classes as a result of computer difficulties.

At Valdosta State University, “Our main systems were not impacted,” said Jessica Pope, communications and media relations coordinator for the school. “It is business as usual at Valdosta State University today.”

Some hospitals were reporting problems with information transfer systems, and some facilities in Europe were canceling elective surgeries.

In Valdosta, the local hospital, SGMC Health, issued the following statement: “SGMC Health is aware of the Microsoft and CrowdStrike global outage. We did not experience disruption to normal operations, although there were some information technology systems minimally impacted. We are fortunate to have a robust information system with redundancies in place to allow normal operations to continue when situations like this occur.”
