A global outage like this is really quite terrible.
I saw all kinds of complaints from friends in many WeChat groups. Not only were some major websites inaccessible, but many people’s own websites and scripts also stopped working. The actual losses are hard to estimate.

Of course, occasional issues are unavoidable, but a failure with such a massive impact really shouldn’t happen to a company of this scale. And taking more than six hours to investigate and fix the problem was indeed rather inefficient.
