Similar to https://aastatus.net/42480 - BT circuits were affected again overnight due to one of our interconnects to BT dropping. The affected BT circuits dropped and reconnected at around 01:30. When this happens not all lines reconnect to their normal LNS router at our side, and instead connect to the 'backup' LNS - this backup one had too many lines on it so these lines saw a second reconnect at around 6:25 as we forced them to cleanly reconnect properly. We are still investigating the problem with the interlink with BT.
The overnight drop affecting BT circuits was BT emergency work whereby equipment was replaced within their network as a result of the problems earlier in the day https://aastatus.net/42480 This would have affected other ISPs who interconnect with BT in Equinix LD8 in a similar way to ourselves.
