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.

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.
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).
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.
