For a service that is trying to be 'mainstream' I think their blog post is horrible.
There is no way a 'regular user' is going to understand what a shard is, nor should they care. Ok, they explained sharding in laymans terms but then went on to talk about "reindexing the shard to improve memory fragmentation issues"... Woah, that means nothing to 95% of users.
If you experience down time and you want your users to be sympathetic then you got to explain whats going on in terms they will understand. Sure, include a technical explanation at the bottom for those inclined, but not as part of your main body.
