Mobile telecoms operator Three UK has gone down for the second time in 24 hours.
It comes just five hours after the company said that the problems on its network had been resolved, with services in London being restored first, ahead of the rest of the country.
In a tweet at 1pm, it said: "The data issue has been resolved across the UK :-) We're so sorry to those who were affected!"
However, the problems that have dogged the network over the past 24 hours have resurfaced this afternoon.
Users started tweeting their frustration on Twitter from about 5pm today when the data signal, once again, disappeared. Furthermore, some users have suggested that voice calling has also been affected this time, although text messaging appears to be working normally, according to reports:
Chris (@Chrrr77) tweeted: "@ThreeUKSupport Have you got a new guy who keeps turning the wrong plug off at the end of the day? Dead again!"
Stephen Blower (@badbud65) tweeted: "@ThreeUK @ThreeUKSupport Unfortunately, since its been fixed, I've been affected, I wasn't previously. No data connection, since 17:00hrs."
Will Jacobs (@Will_Jacobs_UK) tweeted: "@ThreeUK @ThreeUKSupport Internet gone down again in NE6. 2nd time in 24hrs. This is not good."
Laura Beever (@lauralimey) tweeted: "@ThreeUK @ThreeUKSupport My 3G has gone down again... has anyone else's? Been working since 12 but stopped about half an hour ago."
Fozzy Bear UK (@FozzyBearUK) tweeted: "@ThreeUK @ThreeUKSupport The internet issue has not been resolved across the UK Liverpool is still having issues area around M57 no coverage."
Users have also been critical of the customer service the company has provided during the outage, with users dialling 333 for information being put through to a recorded message, while the @ThreeUKSupport Twitter handled knocked off at 5.30pm, on the dot.
