Kraken has similar problems (regarding often being down). Before that, it was bitfinex who had trouble with withdrawals. And beginning/mid 2017, it was poloniex. I'm afraid there is no exchange (in my experience) who managed to have a flawless experience, and nowhere to go when you're not satisfied with your usual exchange. Maybe decentralized exchanges will help with that? Time will tell.
