Add a public reachability status page
asxpio now probes public hosts tied to each datacenter once a minute
and stores 5-minute rows (bingo_monitor_* tables, granted to the
read-only bingo role). Show them: /:locale/status lists every monitored
site with its current state and a 24-hour bar, /status.json has the
same data, and monitored datacenter pages get a small block.

A site is down only when nothing answered for two buckets. Everything
reads as unknown when the worker is stale or fewer than half of the
control hosts in Russia answer, since probes run from Finland and
filtering can look like an outage. The page says plainly that this is
not an incident record.

Refresh test/schema.sql for asxpio's migration 017.

# datacenterbingo
Public site for datacenterbingo.xyz: a 5×5 bingo card of Russia's largest
datacenters, crossed out on publicly sourced incidents. Ruby/Sinatra,
read-only. Primary repo `git.czsk.it/asxpi/datacenterbingo` (Forgejo, CI and
deploy); `github.com/asxpi/datacenterbingo` is a push mirror.
## Shared with asxpio
Content is edited in the asxp.io admin (`/admin/bingo`, repo `asxpio`:
`lib/bingo.rb`, `lib/bingo_admin.rb`). Both apps use the same Postgres tables
(`bingo_datacenters`, `bingo_incidents`) and the photos under `bingo/` in the
`datacenterbingo-photos` bucket (asxpio's admin uploads them there).
- **asxpio owns the schema.** Migrations live there. After it adds a
bingo migration, refresh `test/schema.sql` (instructions in its header)
and update the models here.
- `lib/bingo.rb` here is the read side of asxpio's: models, `Board`,
`PROVIDERS`, the `T` UI strings, and photo/IndexNow key reading. The
admin side (writes, photo upload and resizing, IndexNow pings, ranking,
seeding, `guess_provider`) stays in asxpio. Keep shared parts in step:
`PROVIDERS`, `Board`, and model methods.
- Prod uses a read-only DB role `bingo` (SELECT on the two tables) and a
MinIO user limited to `s3:GetObject` on `datacenterbingo-photos`. Both
are provisioned by the `storage` repo (`init/`), from the same
`BINGO_*` secrets set on both repos.
## Research
Before adding or changing datacenters, incidents or photos, follow
`OSINT.md`. It covers sources, verification, photo rules (no people, and
renderings only for unbuilt sites) and credit format.
## Layout
- `app.rb`: `BingoWeb`. Routes: `/` (redirect by Accept-Language), `/ru|en|uk`
(card; `?view=all`, `?p[]=provider`), `/:locale/dc/:slug`, `/sitemap.xml`,
`/robots.txt`, `/p/:file` (photo proxy, immutable), `/<indexnow-key>.txt`,
icons, `/healthz`.
- Feeds: `/:locale/feed.xml` (RSS 2.0) and `/:locale/feed.json` (JSON Feed
1.1), the latest 50 incidents, newest first. Item IDs are
`tag:<host>,2026:incident-<id>`, so they stay stable when an incident is
edited. Pages advertise both via `<link rel="alternate">` and in the
footer.
- `/data.json`: every datacenter with names in all locales, specs, pages,
photo credit and incidents with sources. Licensed CC BY 4.0, with the
attribution inside the file. Feeds and dataset send
`Access-Control-Allow-Origin: *`.
- Reachability: `/:locale/status` and `/status.json` (`Bingo::Status`),
plus a block on monitored datacenter pages. They read the
`bingo_monitor_*` tables that asxpio's `bin/monitor` writes (TCP probes
from Finland, 5-minute buckets, control hosts in Russia). States: up,
degraded, down (nothing answered for two buckets), unknown (worker stale,
or under half the controls answering). Not incidents: never cross out a
cell from this alone.
- `config.ru`: `www.` → `BINGO_HOST` 301.
- `views/`: `layout.erb` (CSS and SEO head), `index.erb` (card, provider
filter, dialogs), `dc.erb`, partials. `assets/`: icons.
- Card rules: always 5×5. The bare locale URL is the operational card
(indexed). `?view=all` and provider-filtered URLs are noindex, with
canonical pointing to the bare page.
## Dev and tests
`nix develop`, then `bin/test`. That provisions an ephemeral Postgres and
loads `test/schema.sql`. Run `cp .env.example .env` for a local server
(`rackup`), pointing it at a DB that has the bingo tables.
## Deploy
On push to `main`, `.forgejo/workflows/deploy.yaml` tests, builds with kaniko
to `$FJ_REGISTRY/$FJ_USER/datacenterbingo`, then over SSH writes
`/opt/datacenterbingo/{docker-compose.yml,.env}` and runs
`docker compose up -d`. The container is on the `traefik` and `storage`
networks, and the Traefik router `datacenterbingo` takes `BINGO_HOST` and
`www.`.
Secrets:
| Secret | Purpose |
|---|---|
| `FJ_REGISTRY`, `FJ_USER`, `FJ_TOKEN` | kaniko clone + push (`write:package`, `read:repository`); Forgejo reserves the `FORGEJO_` prefix |
| `DEPLOY_IP`, `DEPLOY_USER`, `DEPLOY_SSH_KEY` | SSH to prod |
| `BINGO_DB_PASSWORD` | read-only Postgres role `bingo` |
| `BINGO_S3_ACCESS_KEY`, `BINGO_S3_SECRET_KEY` | read-only MinIO user |
| `INDEXNOW` | same key as asxpio's `INDEXNOW` (served here, pinged from there) |
