If you're a paying Sentry customer, outages in these windows may count against Sentry'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 Sentry 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.

Frequently Asked Questions
›Is Sentry currently down?
Sentry is currently Operational. CheckUpstream tracks Sentry in real-time across the official status page, RSS / Atom feeds, and community telemetry. Refresh this page for the latest reading.
›When did Sentry last have an outage?
Sentry's last resolved incident started earlier today and lasted 2h 23m (degraded performance).
Sentry's 30-day measured availability is 99.598%, from CheckUpstream's own probes against Sentry endpoints. It is the share of checks that returned the expected response, not a figure taken from Sentry's status page.
›How do I monitor Sentry in production?
Sign up to CheckUpstream and add Sentry 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).
›How does CheckUpstream track Sentry?
We poll Sentry'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.
