Starlancerminecraft-hosting.proGuardian Hosting has been utilizing StatusCake over the past few months to monitor our servers uptime. Recently, we started to use HetrixTools to monitor the network of our cabinet. We're currently on the free plan, just testing the uptime of one of our IPs, and we also use the free IP blacklist tool to ensure our IPs don't get blacklisted. Luckily by using this tool, we managed to find out that every single one of our IPs that were allocated to us were blacklisted, and we found out easily had those delisted. Now, we use HetrixTools to ensure that we can show our clients a report of us maintaining a good network uptime, and a tool for us to make sure our IPs don't get blacklisted, and if they do, to get them delisted.
Guardian Hostingguardian-hosting.comHa - HetrixTools launched the same year (almost the same month!) that I started my website! :) It took me three years to learn about the service and start using it - and now it's been around seven years that I’ve been a happy HetrixTools user.
The service is excellent – it alerts me when something’s wrong so I can fix it quickly, and it doesn’t trigger false alarms (just as important!).
A reliable, silent partner that’s been with me for years – no fuss, no pompousness.
HetrixTools deserves all the praise it gets. I've tried several alternatives, but HetrixTools remains my favourite uptime monitoring tool – and I'd even dare say: it's probably one of the best on the market.
