Re: What causes this?
Well, if they are as 'transparent' as they say they are, maybe wait until we get a post-mortem rather than randomly wonder about it? For all we know their backup and failover systems may have worked brilliantly the last 99 out of 100 times they were needed and we just never knew because they just worked, but just didn't this one time (although if failover had been needed that often maybe something is wrong, but you get my point).
