Ask HN: Why was Square down for 13 hours?
According to `issquareup.com` there was a 13 hour outage yesterday - many API endpoints returned 500 errors, locking customers out of their POS and ecommerce sites.<p>It seems unlikely Square is going to post a full postmortem, but does anyone have an inside scoop on what engineering at Square is like now and how they could have a half-day outage with almost no communication?
