Improvements, improvements everywhere

We improved the uptime calculation method, it is a lot more accurate now. We also put some extra info in the notification emails (hope you find it useful). A monitor is notifying a fail? Move the mouse over the info icon in the status column to find what is happening. We also added lot of small improvements here and there that you will not notice at first sight but will help you to find Port Monitor a better tool :)

More bugfixing!

We are finishing the beta stage, stay tuned and thank you all for the reports!

About us, the uptime maniacs

We are a startup company called Nazaríes IT and located in Spain. This project has been developed using Ruby on Rails (our favorite framework) because we couldn't find a website monitoring or server monitoring online tool that fit our needs.

Please, feel free to contact us with any doubts or issues you find while using it. We will be pleased to help you or fix the issue ASAP. Currently, we are working on adding new features like new website monitoring and server monitoring options, while in the meantime, finishing the iOS app.

If you find this project interesting or useful, please, help us and share it!

Thanks for trusting your uptime in us!
