From around midnight through to 00:30 we saw a number of BT circuits drop and reconnect. We saw traffic decrease on one of our four links to BT, so this looks like a routing or device problem within BT. We're investigating further
This link did drop three times (at 00:11, 00:13 and 00:16). We're investigating the cause with BT as we were not aware of any planned work happening on this circuit.
Service was back to normal by 00:25. Neither us or BT were unable to find a cause for the loss of link, we will monitor the link for further problems.
