We have seen situations where our status check job in a github actions workflow failed to report the status to Statuspage.io. The response from status page says something like this:
Your IP address <github runner IP-adress> has been flagged as a scanner. Scanners are not permitted. If you are seeing this message in error, please contact us at https://support.atlassian.com/contact.
I suppose this might be caused by a lot of actions reporting status, or perhaps github actions actually used for scanning. The range of IP-adresses used by github actions (executed on azure data centers) is updated once a week or so (https://docs.github.com/en/actions/using-github-hosted-runners/about-github-hosted-runners#ip-addresses), but apparently that is not enough.
Using a self-hosted runner is not a good option, since this would bring us back to maintaining our own statuspage machine, which was the reason moving to Statuspage in the first place.
