Network uptime is one of the most critical metrics for any blockchain infrastructure. For Polygon PoS, uptime data published on the official status page shows consistent high availability across all tracked components, making it one of the most reliable Ethereum scaling networks in production.
90-Day Uptime Statistics by Component
As of March 2026, the following 90-day uptime figures are reported for Polygon PoS mainnet components:
- Mainnet RPC: 100.0% uptime
- Node Sync: 100.0% uptime
- Public API: 100.0% uptime
- Polygonscan Block Explorer: 99.99% uptime
- Staking API Mainnet: 100.0% uptime
- Staking UI: 100.0% uptime
- Polygon Portal: 100.0% uptime
The Polygonscan explorer's 99.99% uptime (slightly below 100%) reflects brief periods of database maintenance, including an Amoyscan database synchronization issue resolved in late February 2026, and a scheduled maintenance window completed on March 10, 2026.
Annual Reliability Trends
Since launching in 2020, the Polygon PoS network has maintained an industry-leading uptime record. The network has experienced only three significant outages in over four years of production operation — and in each case, the chain never fully halted. Block production continued through the December 2025 Bor RPC incident, and the July 2025 Heimdall consensus bug was fully patched within one hour.
Polygon PoS: Live for five years, with 99.99% reported uptime and millions of daily active users as of 2026.
Why 99.99% Uptime Matters for Blockchain Applications
For applications built on Polygon — payments platforms, DeFi protocols, NFT marketplaces, and enterprise solutions — network uptime directly determines application availability. A 99.99% uptime SLA translates to less than 53 minutes of unplanned downtime per year, which is well within acceptable bounds for most production applications. By comparison, some competing networks have experienced multi-hour or multi-day outages in the same period.
Developers building on Polygon can further improve their application's resilience by using multiple RPC providers, implementing graceful degradation for RPC failures, and subscribing to the official incident notification channels. Transaction data stored on-chain is never at risk even during RPC outages — only the user-facing query layer is affected.
