Why 99.999% Uptime Matters for E-commerce Automation

"Five nines uptime" gets thrown around as a marketing bullet point. Let's make it concrete.

99.9% uptime = **8.7 hours of downtime per year**. 99.99% uptime = **52 minutes of downtime per year**. 99.999% uptime = **5.2 minutes of downtime per year**.

If your price-monitoring bot goes down for 8 hours during Black Friday, you've missed the most important pricing window of the year. If your sneaker-bot proxy fails for 52 minutes on a hyped drop, that's real money left on the table.

Why proxy uptime is hard

Unlike a web server you control, proxies are distributed infrastructure. A single pool has thousands of IPs across multiple providers, data centers, and network routes. Keeping that infrastructure at five nines requires active health checking, automatic failover, and redundant transit.

What NinjaProxy does differently

We monitor every IP in the pool continuously. Failed IPs are rotated out automatically — you never get a dead connection. Our SLA is backed by credits: if we miss the five nines threshold in any calendar month, you get it back.
