Question 1

Is PubNub currently down?

Accepted Answer

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.

Question 2

When did PubNub last have an outage?

Accepted Answer

PubNub's last resolved incident started 2 days ago and lasted 37 minutes (degraded performance).

Question 3

What's PubNub's 30-day uptime?

Accepted Answer

PubNub's 30-day customer-perceived uptime is 100.000%. The figure is weighted (full-outage = 1.0, degraded = 0.3) so component blips don't collapse the score the way a raw incident-count would.

Question 4

How do I monitor PubNub in production?

Accepted Answer

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).

Question 5

How does CheckUpstream track PubNub?

Accepted Answer

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.
