<li>Google News has been very slow to load</li>
<li>Gmail has been slow to load at times</li>
<li>The Firefox start page has been slow to load</li>
<li>(and this affects me the most) YouTube videos over ~5 min have not been able to load in their entirety, they only partially load and then time out (in the most extreme cases of videos near 10 min long, only the first 30 sec are able to load)</li>
</ol>
<p>It probably is your internet connection. Sometimes, it'll just be slow because of problems with your provider or something. It should fix itself sooner or later. Either that or it's a problem with your computer.</p>
