Grammarlystatus history & uptime
How reliable has Grammarlybeen? We record a status check every few minutes and keep the history — uptime, recent incidents, and the upstream providers whose outages cascade here. We never invent numbers; where we're still collecting, we say so.

% of our checks that found Grammarly fully operational — a degraded check counts against it, because a slow or partly-broken service is not a working one. Down and degraded time are counted at our 5-minute check resolution, so both are approximate. Longer windows fill in as data accrues — we never show uptime we haven't measured.
