Could ISP block website/webservices in mass like this ?
Since months specially after I changed my ISP I notice multiple times strange behavior with web service I use (shared host and VPS) , when using on of my VPS proxy I notice it didn't open blocked websites here ( adults ) making it completely useless,
and later on, I notice many Shared Host services I ordered the connection weren't stable at all, specially when longing into cPanel and using FTP, first I thought this is problem with cheap web host I have, but it's happened to all of them, and when I used VPN (_Avira free extension) the cPanel opens normal and fast .
And most frustrating thing I notice lately they start blocking some free VPN extension (still not 100% sure ) but for example Avira VPN stopped working on all websites Screenshot testing YouTube
and YouTube working again after disabling it
For many of you here Network engineers/experts I ask , Could any ISP uses such stupid blocking methods, even if it's blocks other (legal)service with it
