It seems that your site is just a bit too popular for the host that you have. I'm assuming that you are using the free site that is provided by Geocities.
Every time someone looks at your site, it uses up "bandwidth". They only have so much of it to share around between all the people that have web sites on their systems. Usually, each month or even each day, you are allowed so much of that bandwidth. It isn't just the number of times a page is view but it also considers that amount of information on the page that is viewed. A page with just some text on it will probably use up less bandwidth than a page with a lot of images on it, for example.
The free sites, or even some of the sites you pay for, limit the amount of information that people can retrieve from your site on a daily or monthly basis. If you exceed that, they will shut you down, sometimes just until the next day or the beginning of the next month. If you continue to exceed the limits, they might shut you down all together.
The solutions are to move your pages to another site that will allow a higher bandwidth usage or to reduce the number of hits on your site. With the link in your signature, I'm sure a lot of people hit it. If you pulled it from there and any other places that you have the link displayed, it will certainly reduce the number of hits.
