As of September 06, 2026, the ernie AI API responds in 139 ms p50 (edge, time-to-first-byte) from Asia (Tokyo) — its fastest measured region — with 100% uptime. Slowest is South America (São Paulo) at 412 ms p50.
Is ernie down right now?
Reachable from all 4 regions
Last successful probe Sep 6, 17:15 UTC · every 5 minutes from 4 region(s)
Every probe from every region reached the ernie API successfully in the last 72 hours. Measured from outside ernie’s own network, independently of its status page; full log: measured AI API incidents.
Real requests: not measured for ernie — 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.
ernie publishes no machine-readable status page, so there is nothing to cross-check against.

Was ernie down in the last 3 days?
No. All 3,454 probes from 4 region(s) reached the ernie API in the last 72 hours.
What ernie’s own status page reported
ernie publishes no machine-readable status page, so there is nothing to set against the measurements above.

One panel per region: the line is the hourly p50 edge latency (shared scale, ms), the strip beneath it is the outcome of that hour’s host probes. Hover any hour for the numbers. Flat is good; a rising line means the endpoint is slowing down from that origin, a gap means no probe succeeded in that hour.

Measured from Asia (Tokyo), ernie responds in 139 ms; from South America (São Paulo) the same API takes 412 ms — 3.0× 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 ernie’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
ernie’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 ernie’s
own reports are shown next to the measurements rather than folded into them.
