I self hosted many websites for about 20 years, but sadly I had to take it all down this year. In the process of moving to another state. Also going to really miss my 1gbps unlimited fiber connection.

I hosted my websites from windows server 2003, 2008, virtual machines, Linux, and other ways. It was fun times. I have very good up time using 2 servers and UPS battery backups.

Can I just block the 3rd party company URL on my router?
