Downtime like this can be refundable
If you're a paying PubNub customer, outages in these windows may count against PubNub'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 PubNub 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 PubNub currently down?
PubNub is currently Operational. CheckUpstream tracks PubNub in real-time across the official status page, RSS / Atom feeds, and community telemetry. Refresh this page for the latest reading.
›When did PubNub last have an outage?
PubNub's last resolved incident started 6 days ago and lasted 1h 38m (degraded performance).
PubNub's 30-day measured availability is 100.000%, from CheckUpstream's own probes against PubNub endpoints. It is the share of checks that returned the expected response, not a figure taken from PubNub's status page.
›How do I monitor PubNub in production?
Sign up to CheckUpstream and add PubNub 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 PubNub?
We poll PubNub'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.
