LINX have confirmed that these link flaps where caused by an engineer working on other nearby circuits. They have apologised for the unintended momentary disruptions to our circuit.
While such cases of human error are rare by our suppliers we are investigating options to further mitigate any similar incidents in the future.

Investigating
Our peering circuit to the LINX Juniper LAN went offline and returned a few seconds later which dropped traffic at our peering1 router. The circuit is back up and routing traffic, we are investigating the route cause and are speaking to LINX regarding the matter. We will provide updates shortly.
