A lot of topics have been created (or resurfaced) today about 502 Bad Gateway issue.
Earlier today, there was a technical issue on our hosting cluster causing outages on a large number of websites. However, at the time of writing, all posted websites are back online. We’re sorry for any inconvenience caused.
We’re also sorry for this issue occurring multiple times in the last few months.
That said, I’m happy to say that lots of work is being done behind the screens to upgrade the infrastructure which should prevent these issues from happening again. I can’t guarantee this is the last time you’ll see a 502 error, because the upgrade hasn’t been rolled out yet. However, we hope to release this upgrade as soon as possible so please bear with us until it’s done.
