# Browsers and dedicated IPs

> Regions, IP checks, sleeping and deleting.

## Regions

A browser lives in one region and keeps it permanently, together with its dedicated IP: websites see an address in that region’s country, and the browser’s clock uses the region’s timezone. To use another region, create another browser.

Choose the country your IP must be in first. Among the regions there, the one closest to you feels most responsive. The region list helps with both:

- Latency: the round trip from your network to the region, measured in your browser when the list opens. A value marked ≈ is an estimate from your approximate location until the measurement finishes. Under about 80 ms feels local; above about 160 ms, typing and scrolling lag noticeably.
- Available: the region can take a new browser now.
- Limited: you can create here, but AWS was short of machines in the region in the last half hour, or only one place is left. Creation tries other zones of the region automatically and may take longer.
- Unavailable: no new browsers right now (no space left, or paused while we fix a provider problem). Existing browsers there keep working.
- Not yet tested: the region passed our setup checks, but no browser has run there yet. You can create one; if it does not start, choose another region.
- Fastest for you marks the nearest region that is available.

> **Note:** AWS does not publish how many machines are free. Availability comes from your account’s regional limits and how recent launches in the region went, so a Limited region usually still works.

## Basic and Premium

Where Premium is offered, you choose the machine when you create a browser. Basic runs on 2 vCPUs and 4 GB of memory; Premium on 4 vCPUs and 8 GB, so busy pages and many tabs have more room. That is the only difference: the live view, the IP, storage and data work the same way. Premium has a higher running rate; the IP, storage and data rates are the same. A browser keeps its machine for life; for the other one, create another browser.

## The dedicated IP

Each browser gets a public IPv4 address reserved for it alone. It stays with the browser until you delete it and is never given to another customer, even afterwards.

Every few minutes, the browser checks from inside Chrome which address websites see. If the address is ever different, we pause its network at once so that no other IP is used, and the browser shows that it is checking. You can run a check yourself from Settings → Verify IP while it runs.

## Sleep and auto-sleep

An idle browser goes to sleep after the time in Settings → Auto-sleep (10 minutes by default; shorter saves money). A changed setting counts from the moment you save it. Before it sleeps, the live view shows a countdown with Stay awake. Its computer is stopped while it sleeps; the IP and storage are kept, and are still charged.

Never sleep keeps a paid browser running, and charged, while nobody uses it. It is available after your first top-up, when your available credit covers 24 hours of everything your browsers spend with this one always on. Before you turn it on, Settings shows what 24 hours of continuous running costs in the browser’s region: compute, IP and storage. A Never sleep browser still stops when your available credit runs out, or when an administrator stops it or a security check pauses it, and it never restarts by itself: you open it again when you choose.

## Deleting a browser

Deleting is permanent. Access closes immediately, its data and sign-ins are destroyed and its resources released. Charges stop when deletion starts. Encrypted profile archives become unreadable before they are removed.

## Status messages

- Waiting for capacity: the cloud provider has no free machines of this type in the region. We keep trying; your data and IP are safe.
- Provider issue: the cloud provider is having problems in the region.
- Needs attention: something went wrong that needs an action, such as restarting the browser. The message says what.
- Failed: the browser could not be created. Try again creates a replacement.
