MTN explains data services downtime

A number of MTN subscribers complained throughout 2 January 2011 and 3 January 2011 today that the operator’s 3G network seemed to be offline in certain regions.

This downtime included the network’s BlackBerry Internet Service offering.

Earlier this morning MTN announced via Twitter that it is aware of the problem and is attending to it.

“We are experiencing problems with our 3G network. Our technicians are working on it & we will inform you when the prob is fixed,” MTN said.

According to Devan Chetty, acting chief technology officer at MTN SA, the problem arose yesterday morning (2 January) and should now be resolved. However, MTN are still figuring out what caused the issue.

“We experienced a failure in the Newlands SGSN [Serving GPRS Support Node] at around 11:00 on Sunday. This is the node controlling data access for Bloemfontein, West Rand and areas of Johannesburg,” said Chetty.

Chetty explained that the node couldn’t be recovered, “Despite intervention of our top engineers and the supplier’s product development units.”

“All the traffic had to be rerouted to other SGSNs which is an extensive task and kept us busy throughout last night and this morning. At this stage all traffic has been rerouted and further investigations are under way to determine the cause of failure. We are also monitoring the reserve nodes for load and capacity constraints,” he concluded.
