Is the Fireworks AI API down? Live status, latency & uptime by region
Last verified October 22, 2026 · rebuilt about every 30 minutes
Is the Fireworks AI API down right now? Reachable from all 4 regions
Last successful probe Oct 22, 03:46 UTC · every 5 minutes from 4 region(s)
3 isolated failure(s) in the last 72 hours, the most recent (host probes) visible from only one region (Europe (Germany)). A single-region failure cannot be separated from a problem on that network path, so it is not called an outage. Measured from outside fireworks’s own network, independently of its status page; full log: measured AI API incidents .
Real requests: not measured for Fireworks AI — only the API host is probed here, so errors limited to specific models are invisible to these probes. That is exactly what a status page tends to report, hence the line below.
Fireworks AI publishes no machine-readable status page, so there is nothing to cross-check against.
As of October 22, 2026, the fireworks AI API responds in 18 ms p50 (edge, time-to-first-byte) from Asia (Tokyo) — its fastest measured region — with 100% uptime. Slowest is South America (São Paulo) at 252 ms p50.

Was Fireworks AI down in the last 3 days?
No. 3 isolated single-region probe failure(s) were recorded, none of which meets the bar for an outage (two or more regions at once).
Oct 21, 10:41 UTC Europe (Germany) only — not an outage · under one 5-minute probe cycle · 1 failed probe(s) · [Errno 101] Network is unreachable Oct 20, 15:36 UTC Europe (Germany) only — not an outage · under one 5-minute probe cycle · 1 failed probe(s) · [Errno 101] Network is unreachable Oct 19, 11:41 UTC Europe (Germany) only — not an outage · under one 5-minute probe cycle · 1 failed probe(s) · timeout

What Fireworks AI’s own status page reported
Fireworks AI publishes no machine-readable status page, so there is nothing to set against the measurements above.
Is Fireworks AI getting faster or slower?
Right now Fireworks AI is slower than usual from Asia (Tokyo): 37 ms against a three-day typical of 21 ms.
Endpoint response (TTFB) · milliseconds · lower is faster
Last 72 hours · UTC · newest time on the right · current hour is incomplete.
Each line shows a region’s typical response per hour (p50), using the same scale. A gap means no successful timed probe in that hour.

fireworks — hourly p50 edge latency (ms) and probe outcomes per region, last 72 hours Endpoint response time in milliseconds. Lower is faster. Each region uses the same vertical scale from 0 to 500 ms. Lines show hourly p50 values; gaps have no successful timed probes. Outcome counts are listed after this chart.

Chart details The strip shows endpoint probe outcomes, not model-request success. Adjacent hours with all successes or no data are joined. Hover an hour for its recorded values.
Latest is the most recent hourly p50 with data. Median is the median of hourly p50 values over these 72 hours. The “slower than usual” label means latest is at least 25% above that median; it is a relative change, not a fixed speed rating.

Measured from Asia (Tokyo), fireworks responds in 18 ms; from South America (São Paulo) the same API takes 252 ms — 13.8× longer for an identical request. That difference is the network path, not the model, and it applies to every call you make.
What is actually being measured here?
A probe in each region opens a real connection to fireworks’s own API host every five
minutes and times DNS resolution, the TCP handshake, the TLS handshake and the first byte of the
response. Nothing is routed through a gateway or aggregator, so these figures describe
fireworks’s infrastructure rather than a reseller’s. Uptime counts a probe as failed only when the
service genuinely fails — a 401 from an unauthenticated probe means the endpoint answered
correctly and is counted as up.
What this page does not tell you
These are edge latency numbers: the time before the model begins generating. They
say nothing about answer quality, throughput, price, or how long a full completion takes — those
depend on the model you call. Edge latency matters because it is unavoidable: it is paid on every
request, before a single token exists, and no prompt engineering removes it. Where an API key is
available, inference time-to-first-token is measured separately and shown on the region pages with the
model named next to the figure. Likewise, an unauthenticated probe cannot see errors that hit only some
models or some accounts — the kind a status page usually reports — which is why Fireworks AI’s
own reports are shown next to the measurements rather than folded into them.
