Trouble Loading Pages

I have been having trouble loading pages on this site.
It can take 5 to 20 seconds for a page to load.
It usually takes 2 seconds and sometimes 3.
I use edge, firefox, and vivaldi.
All have to same problem that was not there until last few days.
I have an ssd drive that is only 10 percent full.
Nothing has been changed on computer.
I use windows defender, malware bytes, mrt, and glary utilities.
I have spectrum internet, ping 40, down 113 up 10.
No clue as to why it is happening.
It is not happening on other sites, it seems to be specific here.
