Is the aleph-alpha API down right now?

Reachable from all 4 regions

Last successful probe Oct 21, 20:16 UTC · every 5 minutes from 4 region(s)

1 isolated failure(s) in the last 72 hours, the most recent (host probes) visible from only one region (South America (São Paulo)). A single-region failure cannot be separated from a problem on that network path, so it is not called an outage. Measured from outside aleph-alpha’s own network, independently of its status page; full log: measured AI API incidents.

Real requests: not measured for aleph-alpha — 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.

aleph-alpha publishes no machine-readable status page, so there is nothing to cross-check against.

As of October 21, 2026, the aleph-alpha AI API responds in 100 ms p50 (edge, time-to-first-byte) from Europe (Germany) — its fastest measured region — with 100% uptime. Slowest is Asia (Tokyo) at 556 ms p50.

Was aleph-alpha down in the last 3 days?

No. 1 isolated single-region probe failure(s) were recorded, none of which meets the bar for an outage (two or more regions at once).

What aleph-alpha’s own status page reported

aleph-alpha publishes no machine-readable status page, so there is nothing to set against the measurements above.

Is aleph-alpha getting faster or slower?

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.

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.

How fast is the aleph-alpha API from each region?

Endpoint response (TTFB) · last 24 hours · milliseconds (ms) · lower is faster.

How to read these metrics

Endpoint response (TTFB)Network connection and the first response byte, without model inference.

Typical · p5050% of successful timed samples finish within this time.

Slower · p9595% of successful timed samples finish within this time.

Region	Typical (p50 TTFB)	Slower (p95)	Uptime
Asia (Tokyo)	556 ms	661 ms	100%
Europe (Germany)	100 ms	208 ms	100%
South America (São Paulo)	447 ms	1017 ms	100%
US (Central)	260 ms	374 ms	100%

Measured from Europe (Germany), aleph-alpha responds in 100 ms; from Asia (Tokyo) the same API takes 556 ms — 5.6× 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 aleph-alpha’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 aleph-alpha’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 aleph-alpha’s own reports are shown next to the measurements rather than folded into them.
