The problem is bigger on the inside than on the outside

An engineer in a data centre in Norway has found his Windows server was suddenly resetting its system clock to 55 days in the future.

The engineer relied on the server to maintain a real-time routing table that tracked mobile phone numbers as they were being moved from one carrier to the other. A jump of eight weeks was a disaster because it caused numbers that had yet to be transferred to be listed as having already been moved and numbers that had already been transferred to be reported as pending.

The engineer known only by the name of Simen reported that with these updated routing tables, many people were unable to make calls, as we didn't have a correct state.

"We would route incoming and outgoing calls to the wrong operators! This meant, e.g., children could not reach their parents."
