Mobile operator Vodafone has apologised to its customers for a "technical fault" which left many of its 12 million UK customers without a network connection last night.
The company, which spent much of yesterday boasting about reaching 100 million subscribers worldwide, had a PR nightmare to clean up after users were left unable to make or receive calls and text messages.
A spokeswoman told vnunet.com that the problem was at the company's mobile telephone exchange mainframe computers in the north west of England which spread across the country.
Effectively, a huge black spot was created in the north west, which had a knock-on effect as users were redirected to distant parts of the UK network.
Although Vodafone maintained that the number of users affected was minimal, customers were cut out as far south as London.
"We've no idea exactly how many customers were affected, but we would like to apologise to those who were," said the spokeswoman.
Vodafone insisted that the network was back up and running, but did not say whether affected users would be compensated.
