The BT network appears to have been struck by another serious broadband outage on its UK platform today, which affected a significant swathe of locations in the South East of England. This includes some parts of London.

The issues, which first started at around 8am this morning (some problems were also being experienced yesterday too), have ranged from a total loss of ISP connectivity to seriously degraded performance. The cause is unknown and we've read a few conflicting reports from different providers.

Most BT based ISPs have reported the fault, which predominantly impacted the operators 21CN broadband platform, although some appear to have been unaffected. The good news is that BT has now managed to fix most of the problems, although some locations may still be experiencing difficulties.

A number of more northern and midland areas are also dealing with an apparently unrelated and somewhat isolated disruption to their internet services.
