At about 15:39 on the 25th we lost connectivity to most US destinations as a result of a failure of a major transatlantic link, TAT-14. This is a 640GB/s link used by several ISPs. The link is a ring, and the South side failed last month and has yet to have repairs completed. The North link failed severing communications completely. At about 07:46 on the 26th we have connectivity to the US restored. This is circumstances beyond our control, but we are reviewing alternative transit feeds as a result of this issue. It seems ISPs which remained connected suffered exteremly slow connectivity as a result of the extra load via remaining links. Sorry for any inconveience this may have caused.
