Reachability by region

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 all 18 regions to find out where it breaks.

Arduino outage FAQ

Is Arduino Cloud down for everyone or just me?

Check status.arduino.cc against the per-region measurements on this page. Arduino tracks Device connectivity separately from the IoT Cloud UI, so a dashboard that loads while boards stay offline is a real and common split rather than a contradiction. If both the status page and our regions look clean, the more likely cause is the network the device sits on, particularly on Wi-Fi boards behind a restrictive firewall.

Does my Arduino board stop working if Arduino Cloud is down?

No. A sketch already flashed to a board runs from the board's own memory and keeps executing its local logic through a Cloud outage. What stops is everything that depends on the link: Cloud Variables no longer sync, dashboards stop updating, triggers and scheduled tasks that rely on the service do not fire, and you cannot push new firmware over the air until connectivity returns.

Will I lose sensor data recorded during an outage?

Historical data ingestion is a separate component on Arduino's status page, so data collection can fail while other parts of the service work. Readings a device could not deliver are not queued indefinitely by the platform, so treat a long ingestion outage as a gap in the series. If the data matters, log it locally on the device or to an SD card rather than relying on the Cloud as the only store.

Can I still write and upload code during an Arduino Cloud outage?

Yes, if you use the desktop IDE rather than the browser Editor. The Editor and the Cloud Agent that connects it to a board over USB depend on the service, so a browser upload fails during an outage. The offline IDE compiles and flashes locally over USB with no service involved, which makes it the reliable fallback when Arduino Cloud is unavailable.

How we measure this

We request Arduino's public endpoint every 6 hours from Fly.io regions across six continents — 8 of them answered the most recent check.
A region counts as down only when it gets no usable HTTP response. A 403 or 429 means 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.
