People around the U.S. experienced some internet downtime on Monday. The outage was brief and service has been restored.
The culprit was a configuration issue from Level 3, a telecommunications and internet service provider owned by CenturyLink. In a statement to CNN Tech, CenturyLink said a “configuration error” disrupted service and technicians restored service in 90 minutes.
CenturyLink ( declined to provide further details. )
Though Level 3 was responsible for the issue, it affected other internet providers like Comcast. That’s because Level 3’s infrastructure delivers content for other internet services.
Comcast ( said the service disruption to its Xfinity internet service has been resolved. )
According to reports from Down Detector, a website that monitors internet outages, Comcast and Level 3 connectivity was impacted nationwide beginning around 10 a.m. Pacific.
Other internet service providers including Spectrum, Verizon, and AT&T showed a spike in connectivity issues, too, though they were not as widespread. (AT&T has agreed to acquire CNN’s parent company Time Warner, and the deal is pending regulatory approval.) It’s unclear if the spikes were related to the Level 3 outage.
The website does not provide numbers of people affected.
Following public complaints of widespread outages, rumors temporarily circulated online that the outage was a coordinated hack of some sort. But, as CenturyLink confirmed, it was a misconfiguration.
CenturyLink completed its acquisition of Level 3 earlier this month.
