Redis Cloud is the fully managed database service from Redis (formerly Redis Labs), providing hosted Redis and Redis Stack instances across AWS, Google Cloud, and Azure. Redis serves as the world's most popular in-memory data store, used by millions of developers for caching, session management, real-time analytics, message queuing, and leaderboards. Redis Cloud offers Active-Active geo-distribution for global applications, auto-tiering between RAM and flash storage, and built-in search, JSON, time series, and graph data capabilities through Redis Stack modules.
Redis Cloud outages typically involve cluster failover events during node failures, network partition issues between cluster nodes, and memory capacity warnings that trigger eviction policies. Connection pool exhaustion under high client load causes application-side connection errors that mimic platform outages. Active-Active replication lag during cross-region syncing can cause data consistency issues. Maintenance operations like version upgrades on shared infrastructure occasionally cause brief connection interruptions across tenant databases.
When Redis Cloud goes down, applications lose access to cached data, session stores, and real-time data structures simultaneously. Cache misses flood origin databases, potentially causing cascading failures as backend systems receive traffic spikes they were not designed to handle. Session invalidation logs users out across applications. Real-time features like leaderboards, rate limiters, and pub/sub messaging systems fail. The performance impact of losing the caching layer often exceeds the direct impact of the Redis outage itself.
Use this page to check Redis Cloud availability. Redis Cloud outages can be region-specific and cluster-specific. Check status.redis.io for the official status page. If you experience connection timeouts, verify your client connection configuration and network settings before assuming a platform outage.
Redis Cloud with persistence enabled stores data on disk, so data survives node failures and restarts. Active-Active databases maintain replicas across regions for disaster recovery. However, in-memory-only configurations may lose recent writes during unexpected node failures. Always enable persistence (RDB or AOF) for data you cannot afford to lose.
When Redis is unavailable, cache-dependent applications fall back to direct database queries, dramatically increasing database load and response times. Applications without proper fallback handling may crash entirely. Rate limiters backed by Redis stop functioning, potentially allowing traffic floods. Session-based applications log out all users simultaneously.
Use Redis Cloud's Active-Active deployment for geo-redundant replication. Implement connection pooling with proper retry logic in your application. Add circuit breakers that serve stale cache data or degrade gracefully when Redis is unreachable. Consider a local in-process cache as a first-level cache to reduce Redis dependency.
