afaik Brightbox have multiple physical data centre locations, so you can do the same kind of multi-zone deployment you can with EC2 in the US. Linode have one data centre, it will obviously have diverse power and connectivity but it's still one physical location (remember, even Rackspace who clearly have diverse everything still have downtime in their flagship data centre which is one physical location http://en.wikipedia.org/wiki/Rackspace#Downtime)
