twofo: Warwick filesharing

There is an issue with LINX, a network inbetween twofo and the rest of the world, which causes some people to have dodgy connections to twofo. Here's a message from our ISP:

This is an update to the message we sent to you earlier regarding network problems at the London Internet Exchange (LINX). This is completely unrelated to the issue at RHC on Wednesday.

LINX is where the majority of UK ISPs and content providers connect to each other and exchange traffic. There was a significant problem earlier today at approximately 11:15 which affected LINX, and can be seen at their public traffic statistics by the graph dropping to half the usual levels: https://www.linx.net/pubtools/trafficstats.html

Our network is designed to close down connections that have problems via the BGP protocol, which is what happened. Traffic is then automatically re-routed ver other connections. The network resiliency happened as designed and traffic continued to flow as normal.

There is a considerable amount of network disruption at other UK providers as a result of this problem at LINX, but our service is not affected by this. If you use certain UK providers to connect to us you may see performance adversely affected and also packet loss; this is a problem at the provider/LINX end rather than RapidSwitch.

We would like to emphasise this problem is outside our network, and is completely unrelated to the issue that happened at our RHC data centre on 30th April 2008.
