Figures cover 7 days of our samples (725 for CZ), capped at 30 days — not a full month yet unless it says so. All member states averaged 98.78% over the same window.
When the Czech Republic Was Unavailable
1 separate outage, 15 min of observed downtime in total. Times are UTC. Sampling is every 15 minutes, so each window is accurate to within one interval on each side.
| Date | Window (UTC) | Length | Reported state |
|---|---|---|---|
| Friday, 7 August 2026 | 17:43 – 17:58 | 15 min | Unavailable |
Day by Day
One column per UTC day. The number above a column is the percentage of readings that failed that day; a blank means every reading came back.
The Hours the Czech Republic Goes Quiet
In our samples, the weakest hour is 17:00–18:00 UTC at 96.43% across 28 readings, and the weakest day is Friday at 98.95%. That is a description of what we recorded, not a schedule — treat it as a hint about when to retry, not a promise.

Collecting. A weekday-by-hour grid needs at least 14 days of samples before each of its 168 slots holds more than a reading or two — we have 7. Publishing it now would be showing you noise.
What Happens to Your Checks When the Czech Republic Is Down
Nothing validates against a member state that is not answering — not vatnode, not any other provider, not the tax authority’s own portal. VIES stores no data of its own: every answer comes from the member state live, so there is no cache to fall back on and no way to fake one honestly.
What an API can do is fail in a way you can act on. A CZ outage comes back as VIES_UNAVAILABLE with HTTP 503 — never as “invalid”, which would have you rejecting real customers over someone else’s downtime. Monitoring re-runs the check through the day and tells you when the answer finally lands.
For the Czech Republic there is a second route: vatnode also queries the national tax authority or company registry, so some checks still return an answer while VIES is unreachable. When it does answer, the response carries the registered name and address alongside the validity flag.
Full error semantics are in the API docs. For vatnode’s own uptime rather than VIES, see System Status.

Questions People Ask
- Is VIES down for the Czech Republic right now?
- No. At our last reading the CZ node was answering VIES requests. The reading is at most 15 minutes old, and a member state can drop out between samples.
- Why does a valid Czech VAT number fail to validate?
- If the number is well-formed and the CZ node is unavailable, the failure is upstream, not in the number. VIES returns a service error rather than "invalid", and any provider that turns that into "invalid" is lying to you. vatnode returns a distinct VIES_UNAVAILABLE error with HTTP 503 so your code can retry instead of rejecting a real customer.
- Does the Czech Republic publish a VIES maintenance schedule?
- The Commission publishes a general VIES maintenance notice, but member states take their own systems down without announcing it to API consumers. That is why this page exists: the recorded history shows when the CZ node was actually unreachable, whatever the schedule says.
- Can I still validate a Czech VAT number during an outage?
- Not against VIES. What you can do is queue the check and retry — vatnode's monitoring re-runs a subscription's checks through the day and tells you when the answer finally lands, so a customer is not blocked by a member state's downtime.
- Where does this data come from?
- From the European Commission's own check-status endpoint, sampled every 15 minutes and kept. It is the Commission's view of its member states, not an independent probe, so it can lag a node going down and it describes reachability rather than whether one particular number validates.
