Incidents in the 30 days to 1 Nov 2026

by the day of the first post
  1. OpenAI count only 42
  2. xAI 61 h first post to resolved 36
  3. Cursor 32 h first post to resolved 23

A vendor that posts more often is not for that reason less reliable: each vendor decides what it posts, and how finely. Minutes run from an incident’s first post to the post that marks it resolved. Anthropic, Google, xAI, GitHub and Cursor give the time of every post; OpenAI, Cohere, DeepSeek and Perplexity give the newest post only, so their incidents are counted and not measured.
