This time there was a problem with Alibaba Cloud, which affected okx and gate. Last time, there was a problem with AWS, which affected Binance, Matcha, Huobi, Coolcoin, BitMax and FTX. I would like to ask why you don’t build your own server room, or do more of it. There are several cloud service providers, and you can switch at any time if there is a problem. Is this very expensive?…
