Coinbase WS · connection outage, 4 min on 20 AUG 2026
Coinbase WS — 33% of windows failing over the last minute (conn). up24 opened this incident from its own measurements of Coinbase's public API on 20 AUG 2026 23:12 UTC. It lasted 4 min and ended 20 AUG 2026 23:17 UTC, when the component started answering again.
WHAT HAPPENED
- Coinbase published its own notice.
- up24 opened the incident at outage, conn.
- Coinbase marked its notice resolved.
- The component started answering again. up24 dates the incident from this moment, not from when its clearing rule finished.
HOW IT FAILED
Stream measurements are kept for seven days, and this incident is older than that. The incident itself is permanent; the ten-second windows behind it are not.
A stream has no latency of its own — a feed either delivers or it does not — so this is Coinbase's REST endpoints over the same window, per minute, as the median across them. It answers the question the timeline cannot: whether the rest of the exchange was fine while this feed was down.
DID COINBASE SAY SO?
Coinbase acknowledged the same event 15 min before up24 opened this incident, on 20 AUG 2026 22:57 UTC: “Delayed Sends - Ethereum Network”. Matching is by time window, and their notice is linked so the pairing can be judged rather than taken on faith.
Delayed Sends - Ethereum Network · 20 AUG 2026 22:57 UTC
up24 opened 20 incidents for Coinbase in the last 90 days; 9 fall within six hours of something Coinbase published, and the rest were never mentioned. At the median, Coinbase's own notice came 1h 47m before up24 opened its incident. Pairing is by time alone — nothing checks that a notice is about the fault up24 measured, so the 3 that up24 timestamped first are not scoops. Every entry links to the venue's own notice so the pairing can be judged.
