Three mobile network in the UK experienced widespread disruption for most of Thursday, January 23, leaving many customers unable to make voice calls. This was first flagged at 1:05 p.m. GMT on Downdetector, and it extended to Smarty and ID Mobile, which are both running on the same network infrastructure.
At 11 p.m. GMT last night, that spike on Downdetector dropped dramatically, and as of 8:09 a.m. GMT this morning (Friday, January 24), Three UK has confirmed that the outage is over.
