State of Website Uptime — 90-Day Reliability Report
By the Is it down checker Editorial Team · Auto-refreshed October 28, 2026 · Open data
TL;DR: Across our catalog of 2,688 monitored websites in 63 categories, we recorded 3,819 distinct outage events affecting 304 sites in the last 90 days , totaling 417d 8h of cumulative downtime among the top 25 most-affected services. The category with the most accumulated downtime in this window was Streaming (516 incidents across 22 sites).
Methodology
Every outage in this dataset is a recorded event in our database — we mark a site as experiencing an incident when our automated HTTPS probe fails for two consecutive checks OR when crowd-sourced user reports spike to 5x or more above a 7-day rolling baseline. Total downtime is computed from incident start time to resolution time. Sites currently ongoing at report-generation are calculated up to the rendering moment. For the full methodology, see our methodology page.
Our HTTP probes run from a single US-based data center region (do-nyc3), so regional outages outside our checker location may be under-represented. Crowd-sourced reports help bridge that gap, but the data here skews toward outages observable from North America.
