 The BBC's Technology commentator Bill Thompson did not have any e-mail on Tuesday and he is not best pleased, we think he's only go himself to blame. In the recent article published on his BBC Blog Bill actually refers to the solution; multiple redundant connections, he should consider if being deprived of his internet connection is as devastating as he believes. In truth he probably doesn't really care that much but some companies really do. In a recent survey most small to medium sized businesses rated their internet; by which we assume their email; connection was more important than their telephone line.
In practical terms there are several devices such as the Radware LinkProof application switch that allow a user to use multiple ISP connections to provide highly resilient load balanced connections to the internet. These devices are now becoming aggressively priced to the extent that even a relatively small business using cable and ADSL would be able to create a highly cost effective resilient connection.
Some people however don't get the point, rather like anti virus and firewall solutions were 10 years ago, they still take the attitude that '..it won't happen to me.'
In discussion with a customer recently, we considered that they actually processed at least £40,000 every day over a single Internet connection. They have not invested in the basic infrastructure to provide any kind of fault tolerance on that connection,choosingg to continue with a single ISP, one web server and one firewall. The cost of providing the resilient infrastructure would have been around £50k. Why? one might well ask!
