9. id.getmailspring.com and updates.getmailspring.com are down (error 503)Closed

   This is a frequent and recurring issue that the developer cannot catch on their own. Please set up monitoring for these services so that you are immediately informed in case of an outage — rather than having your customers be the ones to alert you.
