These were never marked resolved, but the platform has since dropped them from its status feed. We keep the record and stop treating them as ongoing: the date shown is the last update the source published, not a resolution time we can vouch for.

Platform incidents, no carrier API impact (19)

Login, dashboard, billing and API-key issues. Real outages if you use the platform's interface, but a broken login page does not mean a carrier's API is failing — so these are listed here and left out of carrier uptime.
