It seems that the London Internet Exchange (LINX) are currently experiencing problems. Our connections to LINX are no longer carrying traffic and this is having an impact on some clients who would normally cross LINX to reach us. We do not currently have information on the precise cause but the issue has been reported by other IPs connecting at LINX.
We will provide more information as soon as we have it, but unfortunately it seems that the problem is outside our network and outside our control.
Effect: Increased latency and packet loss for some routes into the network
