Popular online knowledge trove Wikipedia was back online Monday after a fibre optic cable connection between its two US data centres was severed, causing an hour-long service outage. A cable line linking data centres in the states of Virginia and Florida was severed about 1300 GMT, according to the non-profit Wikimedia Foundation, which operates Wikipedia.org and other
websites. Wikipedia's websites were restored after an hour and the mobile service was back online by about 1535 GMT, Wikimedia said.

Wikimedia has two separate fibre optic lines connecting the data centres, with one connection intended to act as a backup for the other in event of a problem. The data centre in Virginia handles most Wikipedia traffic but accesses the centre in Florida to fetch stored information in the crowd-sourced online encyclopaedia, according to Wikimedia
