One of many factors to consider before you buy a VPS is uptime. Especially if you want to use that VPS to host your high traffic websites. Down time is really really bad and it hurts SEO badly. Hence, it is better to know faster when your sites go down. Remember, an offline website doesn’t earn $$. Ensure you stay online.
Here in this page I compiled several website’s uptime monitoring services those are also offering free plans. Obviously there are downsides of using free plan compared to the premium plans but it is still worth it to try. You may consider to upgrade if your websites get serious amount of traffic and so your revenue 🙂
Let’s start the list with the one that I think the best of all other, meet Pingdom.
Pingdom is not just a web app providing uptime monitoring service but also other useful tools like website speed test, DNS health checker, ping and traceroute. Cheapest plan or their premium plans is available for $6.96 allowing you to have 10 checks plus 20 sms alerts per month. But there is a free plan that lets you monitor one website/server and includes Real User Monitoring. [link]
2. Uptime Robot
This one is also my very favorite. First because it is free (there is no paid plan in fact) and secondly because you can have 50 checks (that means 50 websites/servers to monitor) and each checked every 5 minutes, the shortest interval ever available for free service. Uh and they provide API too. How awesome is that! [link]
