EVE Tools Status

Status page for EVE Online community tools — https://eve-tools-status.com

27 monitors across 6 categories (core services, killboards, market & industry, maps & intel, wormholes, reference), checked every 15 minutes from 4 Vercel regions (iad1, sfo1, fra1, syd1).

How it works

• Four vercel.json crons (*/15 * * * *), one per region, hit /api/check/{region} directly. Each route is pinned to its region via preferredRegion, fetches every monitor URL in parallel and records status + latency. There is no orchestrator in the scheduled path on purpose: a fan-out function spends its whole life awaiting the region it called, which billed a fifth function for the duration of the slowest region on every run
• /api/cron still fans out to all four regions, for triggering a full round by hand
• Results land in Upstash Redis (ets:* keys): latest snapshot, one daily aggregate hash per day (100-day TTL), status-transition events
• UI: Status (45-day uptime bars), Events (incident log), Monitors (live per-region state) + a suggest-a-tool form
• Every page reads KV through a cached loader (use cache, 60s revalidate), so the pages are prerendered and served from the CDN. Data that only changes once per check cycle does not need a function invocation and a 49-command pipeline per visitor

Environment variables

Var	Source
KV_REST_API_URL, KV_REST_API_TOKEN	Upstash KV via Vercel Marketplace (auto-injected on connect)
CRON_SECRET	Random secret; Vercel cron sends it automatically, also guards /api/check/* and /api/debug

Development

npm install
vercel env pull .env.development.local
npm run dev

Trigger a check manually:

curl -H "Authorization: Bearer $CRON_SECRET" https://<deployment>/api/cron

Review visitor tool suggestions:

curl -H "Authorization: Bearer $CRON_SECRET" https://<deployment>/api/debug

Monitors are defined in lib/monitors.ts. Before adding one, probe it with curl — sites behind aggressive bot protection (e.g. Cloudflare) may 403 datacenter IPs and show as permanently down.
