The representative score is a good indicator of reliability and is calculated using various attributes such as uptime, voting weight and days since creation.
Please do not use this score as the sole indicator when choosing a representative.
I am a software developer from northern germany. I run this node on a german hoster I trust with many services. Hosting anything (Email, cloudstorage, etc.) is a hobby of me since some years now. There are checks in place which notify me when there is something up with my node to ensure an uptime of >99% since January 2018. If you have further questions check out the about page on my monitor page at nano.nifni.net.
