[ANN] errors.fail - free service for probing errors

[Daniel Lorch]

Dear all

I have recently started to use Prometheus and blackbox_exporter. My main interest was to build up SLI/SLO dashboards for the services I run. The SLI dashboards are configured to compute the ratio between "all god events" divided by "all events" over a period of 28d, as suggested by the SRE books.

I was looking for a way to get some "probing errors" delivered to blackbox_exporter, so I could see how the dashboards evolved. For this purporse, I could have just spun up a local webserver and configure it to deliver 200 OK and 500 Internal Server Errors, but what I was really looking for was an Internet-accessible service that I could make to do exactly those things.

I started to write some code and evolve it into a service that could be used by other people. This is my Covid-stay-at-home pet project: the service is completely free and all source code is available as OpenSource. I would be curious to receive feedback from the community about it:

Thank you in advance and have a good day.
