Websites are blocked on Comcast network, work outside

I called the security team and did not get any help. They first told me they would transfer me to technical dept, where I had to validate my account info and explain the issue all over again. the techncial team then said they can't even check the website on their end as they are not allowed - how are they supposed to help if they can't even do basic tests?

they wanted to reset my modem, reboot PC etc, none of which is of any help. I asked them to do tracert/nslookup etc and they had no idea what that was, so I have no idea how technical they are, they just want to do basic things off a checklist like a non technical agent would. I can't even get them to understand why only one website is blocked and the internet connection works.

sorry but I am very frustrated at this point, it takes me 2hrs+ just to talk to 2 people, there is no chat support, no email follow up.

@Adent, The only way to report a website being blocked is through the spa.xfinity.com. When did you submit that request? 

more than 2 weeks ago. why would it matter if I have advanced security turned off? are you saying Comcast does other blocking even with it off?

something strange is going on here. the website works sometimes, then it will stop working for days/weeks. multiple urls on the same domain don't load, so its a whole domain that's being blocked.

I spoke with the tech support there and they do no blocking of any kind.

@Adent, Xfinity xFi Advanced Security blocks websites that are determined to be potentially dangerous. These sites may contain malware, spyware, ransomware or viruses that can infect devices and make them vulnerable to personal data collection, blackmail or attacks on other computers and networks. You can find out more information by going to Use Xfinity xFi Advanced Security and how the advanced security works. I would suggest reaching back out to our security team if you put in a request that long ago and have not heard back as you usually get an update provided within three business days. Or you can put in a new request at Reporting Website Being Blocked link.
