What is the impact on my PubNub-powered application due to a data center failure?

The PubNub Network infrastructure is deployed on a global network of redundant data centers spread across multiple geographies with automatic fail-over capabilities to ensure highly-reliable operation of the realtime messaging service. In the rare event of a data center failure, PubNub Pro Plan customers have SLA guarantees (99.999% uptime) that ensure prompt fail-over to the next closest data center until the troubled data center recovers.
