Allowing elmah.io uptime agents
elmah.io Uptime Monitoring runs in 9 different regions. Depending on which regions you enabled on each uptime check, your network infrastructure/firewall, or security settings, you may need to allow requests from elmah.io uptime agents.
You can allow requests by allowing all requests with the following user-agent:
User-Agent: elmahio-uptimebot/2.0
Allowing requests by possible inbound IP addresses is also an option. Since we run on Azure these changes over time, but here's a list by region as of time of writing this article:
