Having an issue with the site

So for the past few days, I’ve been having a recurring issue with our site and I want to ask if anyone else is having any problems. The issue at hand is the site operates like normal one day in a normal Firefox browser, and then - when I update the page to new replies to threads - the page seems to take an extra long time to load or simply doesn’t load at all. How I’m able to reply right now is by using a Private Browsing window. So I’m just asking if anyone else is having the same or a similar problem, of if it’s just my browser or computer?

I’m using chrome on a phone. No lag, no issues.

Some internet issues may be caused by certain ISPs throttling connection speeds in areas with high numbers of people needing free internet for distance learning. Some sites I visit have had that issue in my area of Asheville NC
