While Thursday’s AT&T outage grabbed national headlines, outages do happen and usually for mundane reasons, several telecom experts told CNN.
Common causes include construction-related digging that punctures fiber optic cables and software misconfigurations that can lead to interruptions, said TJ Kennedy, a public safety communications expert.
“I can’t think of every incident in the last few years, but I can think of things related to routers, things related to backhaul, things related to software,” Kennedy said. “This has happened across all major carriers, multiple times in the past few years alone.”
Thursday’s outage could have been caused by human errors in AT&T’s cloud-based networking system, said Lee McKnight, an associate professor at the Syracuse University School of Information Studies.
“The dirty secret of telecom networks these days is they are just a bunch of wires and towers connected to the cloud,” McKnight said. “Someone making a mistake, and others on their team — and their automated tools — not catching it, is quite common in cloud computing.”
