BT is telling ISPs the reason for the multi-hour outage was
a software bug in the interface cards used in BT's core network.
BT installed a new version of the software. When that didn't fix
the problem, they fell back to a previous version of the software.
BT didn't identify the vendor, but BT is identified as a "Cisco Powered
Network(tm)." Non-BT folks believe the problem was with GSR interface
cards. I can't independently confirm it.
