There are some website that are good with strong network while some can open with even weak network. And probably r_victory location network is weaker than the site but can open other sites. It happens sometimes.
What do you mean by a stronger or weaker network? Are you referring to the speed or distance between the server and the user?
I visited the website with multiple VPNs and it seems like there are no major issues. That being said, I remember that my country's network suffered heavy throttling because a fiber cable got attacked by sharks. I don't think that's the cause if the problem happens specifically to one or two websites though.
