Downtime like this can be refundable
If you're a paying 100ms customer, outages in these windows may count against 100ms's SLA — vendors owe service credits for missed uptime targets, but only if you file inside the deadline. CheckUpstream tracks the entitlement, drafts the claim, and hands you the filing link.

A 100ms outage only matters if something you ship depends on it. Point us at a public repository and we will read its dependencies and tell you — no account, nothing stored.

100ms's 30-day measured availability is 100.000%, from CheckUpstream's own probes against 100ms endpoints. It is the share of checks that returned the expected response, not a figure taken from 100ms's status page.
Sign up to CheckUpstream and add 100ms to a watchlist. We send incident alerts via Slack, email, webhook, or PagerDuty within seconds of detection, covering both the official status page and community signals (HN, Reddit, Bluesky, Cloudflare Radar).
We poll 100ms's official status page on a 1-5 minute cadence, parse its RSS / Atom feed as a fallback, ingest community signals from social platforms, and aggregate per-org SDK telemetry. Multiple sources reduce false positives versus any single feed alone.
