The forum's host server has been running smoothly, so I doubt that would be causing you to have slow connection problems. For example, you can see that there are many new posts and other members online while you have been unable to access the site.
Your computer does not connect directly to the forum .. it will be routed through a number of network connections, called "hops". In my own case, there are 15 hops between my computer in Ontario Canada, and the forum's host server, which is located in Texas. Sometimes there will be "hangs" at one or more of the hops in between me and the host server, including my own local service provider.
That being said ...
Some of the biggest contibruters to hanging or slow loading of forum pages are images that are linked to another website .. especially the weight loss tickers and twinkly "glitter fonts" in member signatures. If those websites are slow, then it will take a long time to download the images in a thread on our site. You could try disabling images to see if that helps speed up page loading.
To disable images, go to your user Control Panel .. User CP on the left side of the menu bar above this thread. Choose Edit Options from the left menu, then in the Thread Display Options section, uncheck the Show Images box, under Visible Post Elements. Be sure to click the Save Changes button at the bottom.
I do this every now and then, especially when reading long threads that have a lot of images, signatures with tickers or twinkly stuff. It's easy to switch images on and off. When you have images turned off, they will be replaced by a clickable link .. so you can click the link if you'd like to see the image
Just a thought
