Nightly check of public ELMAH pages
We still see users accidentally publishing their ELMAH endpoints to the public (here’s why you don’t want that). That is the simple error browser on /elmah.axd or /elmah the open-source library ELMAH provides when logging to elmah.io from ASP.NET. To help take action if this happens we have extended uptime checks with a toggle to check this nightly. If we find a public ELMAH page we will log an error in your log.

The feature is available on Enterprise plans and only makes sense to enable if you are logging from Webforms, MVC (not ASP.NET Core MVC), or Web API.
