Didn't have a good experience with them. One day we suddenly started to experience severe latency spikes, lasting for more than a day, causing timeouts. Unrelated to our DB which was small, even happened on trivial queries - a networking thing on their side. Google showed this to have happened before with certain regions of theirs. If you can't offer a certain region in a stable manner as a DB vendor, don't offer it. The whole point of outsourcing DB mangement is to take care of these things.
