TL;DR possible 1 min downtime
Some shared hosting instances reported getting random 500 errors that got fixed after restarting the services. The only thing in common between them is the App Server that they are hosted in. As a preventive measure, I will be restarting the services of all instances on that server. It will be a one minute downtime and only a small percentage of instances are located on that server.
Please do report if you noticed random 500 errors on your instance. Thanks
