My PaaS provider had decided to update their platform late that evening. This caused an obscure bug which kept my Docker containers from spinning up again. The consequence was devastating: My was offline for hours. I had no way of fixing a bug over which I had no control. app I could only email everyone and apologize in person. Worse yet: I had no good way of letting my users know what was going on. Why Monitoring Is Not Enough Here’s an email you don’t want to get at 11:24 PM Of course I had set up automatic monitoring of my app’s web page and API endpoints. But it’s not enough if know that your server is down — unless you’re the only one using it! If anyone else is depending on your service, you you need to have a communication channel (not if!) something goes wrong. when A status page can be an important element in your relationship with your users. It helps you achieve the following goals: Be open about what’s gone wrong and what you’re doing to fix it Transparency Publish information and updates about service interruptions right as they happen Fast crisis response Being transparent and responsive is the best way to show your users that they can trust you.

This is why I decided to set up my own status page. I’m sure this pricing makes perfect sense for VC-backed Silicon Valley companies — but not for bootstrapped startups or freelancers like myself. What Do We Want? There are really three boxes that a good status page needs to check: ☐ The status page needs to be able to display monitoring and/or performance data from external sources Automatic updates from monitoring services ☐ The main purpose of a status page: Communicating the availability of your services to your users Communication of current status and planned maintenance ☐ Well, obviously! It needs to look good The Solution? Fortunately, there is an open-source (Apache-2.0-licensed) status page that fulfills all my requirements: . .
