Incident
Report for GitHub
Resolved
An update to our design system caused issues loading dynamic content in the global side navigation menu and in other page-specific sidebar navigation elements. Impacted users saw continuous loading spinners in place of dynamic menu content. User impact lasted from 0:55 UTC to 4:41 UTC on February 1st.
We are working on a number of improvements in response to this incident. We are adding request volume monitors to sidebar navigation endpoints and making changes to our front end escalation paths to improve our time to detect and time to recovery for incidents of this nature. We have also begun work to improve both automated and manual testing for these types of changes in order to prevent recurrence.
