Network connectivity is returning to normal, and the affected services should no longer be impacted. We will continue monitoring the situation closely. If you continue to experience similar issues, please contact our support team at support@semaphore.io.
identified
Our investigation has identified intermittent connectivity issues between our infrastructure provider’s network and certain Google services. This may affect artifact uploads and downloads, as well as jobs that depend on Google-hosted resources. We’ve gathered diagnostic information and are escalating the issue to our infrastructure provider for further investigation. We’ll continue monitoring the situation and share updates as significant new information becomes available.
investigating
We are continuing to investigate this issue.
