At 10:26pm UK local time, we started to receive automated reports of increased latency and packet loss to some destinations. After some diagnostics, we discovered that traffic taking an inbound path via Cogent (AS174) to us was seeing increased latency of +900ms and 25-35% packet loss. Outbound data was unaffected….

At approx 8:25pm on 30th May 2024 we identified some network disruption to our core network. After investigation, we discovered that we had lost power to a rack in Manchester that houses some connectivity and also one of our core routers. Generally this would cause a couple of minutes of… Continue reading
We’ve noticed some instability of peering connections between our router and LINX LON2 network which has caused a few periods of packet loss and latency to some locations. This does not seem to be affecting our LINX LON1, LINX MAN1, or Equinix-IX Manchester peering groups. We have temporarily shutdown our… Continue reading
We have detected increased latency for paths travelling via AS3257 (GTT) to/from the global internet. This seems to be intermittent at the moment. We have reduced our reliance upon this circuit to try to reduce the effects of this increased latency. If we continue to experience any issues relating to… Continue reading
At 12:14am UK local time, our monitoring reported an outage on two Vodafone provided fibre circuits delivered into our BOL8 location. These are both delivered over the same fibre bundle. These circuits provide our main office telephone service, and one of our metro ethernet fibre ring legs. After internal investigation… Continue reading
At 12:12pm today, our monitoring reported a failure of our VirginMedia metro ethernet leg within our metro ring. We have raised this as a fault with VirginMedia for investigation. We have a resilient ring so no outage or degration of service is in effect, only a reduction in resilience.
At 10:03am this morning, we saw a collection of BGP connections drop in Equinix MA1 (Manchester). These were spread across LINX MAN1, EquinixIX, and our GTT IP Transit connection. This caused a couple of minutes of instability whilst BGP reconverged and rerouted traffic automatically. A few minutes later, we saw… Continue reading
We’re currently seeing one of our core fibre ring circuits offline (provided by Vodafone) between Manchester and Bolton. We’re not aware of any routine maintenance by Vodafone on this circuit so will proceed to investigate it as a fault. Due to our ring nature of the core, all traffic automatically… Continue reading
Our office voice fibre circuit is currently showing a fault and we have raised this with Vodafone who are investigating. This affects any Netnorth telephone lines including our emergency support line. If you require assistance, please e-mail support@netnorth.co.uk (even if from an unauthorised email address) with your contact details and… Continue reading
LINX (London Internet Exchange) are experiencing issues with their LON1 network today. This is causing brief periods of instability and BGP session outages across their network and has been seen across multiple switches now. As a result, we have shutdown our LON1 peering until LINX confirm the issue is resolved…. Continue reading
