COLUMBIA — Mediacom customers all over the country experienced service outages Wednesday afternoon.
Internet and phone customers lost service at about 4:45 p.m. when Mediacom's multiple Domain Name System servers, which allow customers to access the Internet, was flooded with a high volume of incoming traffic and stopped relaying connections, Mediacom communications director Phyllis Peters said.
The traffic likely came from a person phishing or sending mass emails, but Mediacom is still investigating the cause of the traffic, she said.
Because of the blocked traffic, three of Mediacom's servers had to reconfigure and rematch customer account numbers before service could be restored. The final server, which provides service to Missouri customers, was fixed by about 7:30 p.m.
"This kind of service interruption is rare," Peters said.
This is the second time this week Mediacom services have gone out. Monday night's storm cut lines in mid-Missouri, causing an Internet outage for Mediacom and another Internet provider with which it shares the lines.
The Monday night and Wednesday afternoon outages are unrelated, Peters said.
Credit for service outages on Monday afternoon and Tuesday will be awarded to customers on a case-by-case basis, Peters said. Customers interested in receiving credit must call Mediacom's customer service number at 1-855-MEDIACOM or 1-855-633-4266.
Mediacom has not yet determined whether it will offer credit for Wednesday's outage, Peters said.
