Related discussions
I’ve collected these discussions for anyone experiencing similar problems or following the issue. They are grouped by platform and ordered by posting date within each group. All dates are in 2026; activity figures are a snapshot from 19–20 October, not live totals.
These are related reports, not necessarily separate incidents or evidence of a shared cause. Replies and views do not measure the number of affected users. “None seen” refers to public OpenAI Support replies, not private Support contact. Linking to a post does not mean I endorse every explanation it offers, including speculation about deliberate throttling or sabotage.
