Your servers, from the corner of your screen.

When a server fails and no other server has answered since, Atalaia asks two well-known addresses — 1.1.1.1 and 8.8.8.8, on port 443 — whether this machine can reach the internet at all. If it cannot, the overlay says your connection is down, your servers are held rather than blamed, and every clock starts again when the connection returns.

Waking from sleep gets the same courtesy: failures in the first seconds after the lid opens never count.

You will see a blue window headed Windows protected your PC. The button that continues is behind More info — click that, then Run anyway. Some browsers warn about the file before that, for the same reason.

That screen is Microsoft Defender SmartScreen, and it does not mean Windows found anything wrong with Atalaia. It means Windows cannot tell who made it: a publisher proves that by signing its programs with a certificate it has bought, and Atalaia does not have one yet. Every new unsigned program gets this screen, however harmless it is.

You can check the file instead of taking the message's word for it: every release publishes a fingerprint of each download beside it, in SHA256SUMS, and Get-FileHash in PowerShell prints the same fingerprint for a file that arrived intact.

No telemetry, no analytics, no account, no logs on disk. Atalaia contacts three kinds of address: your own servers, as you configured them; the two reference addresses above, only while a server is failing with nothing else answering — a TCP handshake and nothing more; and a small file on this site, a few minutes after it starts and then once a day while it stays open, to see whether a newer Atalaia exists. That check sends nothing about you or your machine, and Automatic updates in the preferences switches it off.

The overlay ignores the mouse so it can sit over anything. Choose Unlock overlay to move it in the tray menu, drag it anywhere on any screen, and press Lock on it. It remembers the nearest corner, so a longer list grows away from the edge you put it against.

The order is the list in Atalaia's window: drag a server up or down there, and the overlay and the tray menu follow.

Everything lives in one readable JSON file, %APPDATA%\Atalaia\config.json. Copy it across, or generate it — hand edits are welcome while Atalaia is closed, and anything out of range is brought back into it. An empty atalaia.portable file beside the executable keeps the configuration in the same folder instead.
