When an outage or slowdown occurs, you’ll be the first to know.
We check your websites, servers and routers 24/7, from all around the world, to make absolutely sure they’re working like they should.
At Alertra, we are industry innovators. We’ve done the hard work of designing a robust, scalable solution to ensure you get alerted on time, every time. Our innovative Alertra Synapse™ technology can detect hard connection failures, equipment lockups and operating system failures within seconds. Nobody else does that. We don’t cache name server lookups either. That means we figure out something’s wrong with your authoritative name server right away, instead of waiting for your TTL (time-to-live) to expire, which could be days.
