Is Arduino Down?
Reachable from all 8 checked regions

Arduino uptime
Measured from multiple regions every 6 hours. Percentages count only checks that returned an availability answer — 27 days measured so far. A dash means that window does not yet hold enough measured days to publish a figure.

Each region runs its own request from a different part of the world. A service can be up for one continent and down for another, which is usually the first sign of a routing or CDN problem.
What Arduino does
Arduino is the open-source electronics platform used across hobby projects, classrooms and industrial prototyping. Alongside the boards, Arduino Cloud is an online service for writing sketches in a browser, provisioning devices over Wi-Fi, LoRa, Ethernet or cellular, syncing Cloud Variables to dashboards and pushing over-the-air firmware updates, which makes it a live dependency for deployed hardware rather than only a development convenience.
What an outage looks like
Devices show as offline in the Cloud dashboard while the hardware itself is running fine, because the fault is in the link rather than the board. Dashboard widgets freeze on their last value as Cloud Variables stop syncing. The browser Editor fails to compile or upload sketches, over-the-air updates will not start, and REST API calls from scripts and integrations return errors.
What to do about it
Check status.arduino.cc, which tracks Arduino Cloud, Editor, IoT Cloud UI and Dashboards, Device connectivity, API Requests, Historical data ingestion, Authentication, Integrations and the EdgeImpulse machine learning tools as separate components. Device connectivity can fail while the Editor holds, and the reverse. Sketches already flashed to a board keep running their local logic, so hardware doing standalone work is unaffected by a Cloud fault.
Is it down for everyone, or just you?
If this page says Arduino is up but it is not loading for you, the problem is between you and them. Run a check against any URL from up to 18 cities across three regions to find out where it breaks.

How we measure this
- We request Arduino's public endpoint every 6 hours from Fly.io regions across six continents — the most recent check ran from 8 of them.
- A region counts as down only when it gets no usable HTTP response. A
403or429means the origin answered and refused us, which we report as blocked, never as an outage. - A single failing region is treated as probe noise. We only change the verdict when two consecutive cycles agree.
- Response times average only the regions that actually served the page, so a timeout never inflates the number.
- Where Arduino publishes an official status feed we read it too. An all-clear from the vendor can soften an unconfirmed degradation; a vendor-declared outage only worsens our verdict when our own checks corroborate it.
