Please add the ability to tag outages. Today there is only an option to mark outage as a maintanence and add comment. We are missing the ability to differentiate outages that were caused by application failures (bugs, deployment failures, ...) from outages caused by infrastructe failures (server failures, webserver missconfiguration, ...). Based on tags we would like to report uptime that include / exclude some of the outages types base on tags, for example the uptime without application failures. Thank you.
