“DES MOINES, Iowa July 7, 2022 — A large number of Iowans could not get online Tuesday afternoon due to a widespread Internet outage. Mediacom, the internet provider whose service went down, now believes it knows the cause of the outage.
“In a statement, a Mediacom spokesperson said the outage was caused by a software bug to a large router operated by a third-party, which left the situation ‘beyond Mediacom’s control. The situation left 40 percent of its Iowa service area without internet at about 3 p.m. on Tuesday.
“The company said it has installed software updates and rebooted its system since the outage.”
