I am having a bit of difficulties accessing the site! It says ERR_CONNECTION_TIMED_OUT. I can confirm that my internet connection is fine. Or maybe your site has some kind of geo level restrictions?
I didn't get any error, but the website has been loading for the last five minutes for me, and it hasn't fully loaded yet. So, I guess it's not only you, but for some specific region. I am saying this based on your edited part. If location changing makes the website load faster, then there is something wrong. I have been writing this post for a few minutes now, meanwhile, it's still loading. I tried to refresh the page, and it's stuck now. I think they should work on it.
I never said that changing the location made the website's loading time faster. It is the same as you described. I am also getting slowness from my side! While I am able to access other sites without any delay, but for ChiliStakes there is a slight late in response time. Also, some of the options were not responding for the first could of time. For example I kept pressing the Casino, Sports, Promotions, VIP. I had to use the, "open in new tab" to view the pages. I guess it was due to the site not loading in properly in time.
