Nick here from Coveralls -- we're actively monitoring this outage but unfortunately entirely reliant on our infrastructure provider to mitigate and bring us back online.
Hi, Coveralls CTO here, the pass/fail status of any commit is shown as a green check / red x in the commit list and at the top of the repo details page as the "most recent commit".
As for a % badge, you can use our new Coveralls GitHub Action to post your coverage data to https://coveralls.io, then add the badge to your readme:
Please follow the status page (https://status.coveralls.io) for updates.
Thank you for your patience here. We'll be back soon.
