About DownOrSlow
DownOrSlow answers one question for ChatGPT, Claude, Gemini and Grok: when one of them seems not to work, is it down, or just slow?
What the site shows
Probes in several countries time the way in to each service every 15 minutes, and each time is set against what is usual from the same place. Beside those timings stands what the provider's own status page says. The two never mix: our timings do not change a provider's statement, and a provider's statement does not fill a gap in our timings. How we measure sets out the method and what it cannot see.
Who runs it
DownOrSlow is run by Grainpeak LLC, a company registered in Wyoming, United States. Reading the site is free and needs no account.
Independence
DownOrSlow is not affiliated with or endorsed by OpenAI, Anthropic, Google or xAI. ChatGPT, Claude, Claude Code, Gemini and Grok are names their owners hold, used here only to say which service a reading is about.
