At approx 6:45am this morning, our monitoring triggered reports of instability for connectivity via our LINX connection (London Internet Exchange) in London.
As this link was not saturated in any way, we took the decision to shutdown the link to cause all traffic to re-route via alternative paths.
This connection is provided to us by a 3rd party, so we will investigate any issues with them directly.
Some customer reports indicate that this problem may have started as early as 4am.
With this connection shutdown, all paths should have returned to being stable now.
Any connections into/out of our network via other paths would not have been affected.
Our LINX ConneXions provider has informed us that they experienced an issue between their LD1 and Telehouse North site which is where our LINX London connection originates.
We will await an RFO from them before bringing the circuit back into operation – although they do claim that the issue is resolved.
