Some sites are slower than others because they are farther away.
A lot of web sites that contain software for you to download have mirror sites, which are copies of the web site in a different part of the world. You can find the mirror site closest to you, and access that site. Another reason why a site might be slow is that the site either has a slow connection to the internet or is totally overloaded with visitors. To check to see if there is a problem with only the site that you are going to, try going to a few other web pages. If they all load normally, then the problem is that the other site is just a little slow right now.
