The signal

Nothing this window changes the picture.

Since last brief

• Anthropic outage cadence: on Sept 3, ChatGPT, Claude, and Grok all hit errors within the same window, with Azure cloud issues implicated as a contributing factor; Claude’s Opus 4.8 and Opus 5 lagged the other models back to baseline, full recovery by 12:38pm PT. Updates the watchlist item (previously “last incident Aug 31”) with a new, multi-provider-correlated incident. Axios (independent) · The Register (independent)
