I'm always beyond impressed with how responsive and transparent CF is with incidence and post mortem communication. Given who the CEO and COO are, I suppose this shouldn't be surprising, never the less as a customer it builds a great deal of trust. Kudos.
Yes, they do really well on this - open, transparent, posting information quickly as soon as they were fairly sure what the problem was. I always really enjoy their writing, both incident reports and writeups of new features. The only thing I think they could have managed better was their status page, which claimed they were up (every service was green) when they were not.
