# Regions

# Regions

Every account is pinned to a single region at creation. Events are stored and delivered
from that region only.

## Available regions

| Region                | Identifier       | API host             | Data residency |
| --------------------- | ---------------- | -------------------- | -------------- |
| US East (Virginia)    | `us-east-1`      | `api.kestrel.dev`    | United States  |
| EU West (Ireland)     | `eu-west-1`      | `eu.api.kestrel.dev` | European Union |
| Asia Pacific (Sydney) | `ap-southeast-2` | `ap.api.kestrel.dev` | Australia      |

> [!INFO]
>
> `api.kestrel.dev` is an alias for the US region, not a global router. An EU account
> calling `api.kestrel.dev` gets `404 account_not_in_region`.

## Choosing at signup

Region is chosen once, during account creation, and cannot be changed afterwards. Moving
regions means creating a new account and re-pointing your subscriptions.

> [!WARNING]
>
> There is no cross-region replication. A regional outage suspends delivery for accounts
> in that region until it clears; events published during the outage are queued, not lost.

## Egress addresses

Deliveries originate from a fixed set of addresses per region. Allowlist the whole block
rather than individual addresses — they rotate within the block without notice.

```text us-east-1

## Latency

Median publish-to-delivery latency, measured over the last 30 days:

| Region           | p50    | p95    | p99   |
| ---------------- | ------ | ------ | ----- |
| `us-east-1`      | 180 ms | 410 ms | 1.2 s |
| `eu-west-1`      | 195 ms | 450 ms | 1.4 s |
| `ap-southeast-2` | 240 ms | 620 ms | 2.1 s |

These are measured to the point Kestrel writes the request, and exclude your endpoint's
own processing time.
