When a web server runs out of disk space all sites being hosted on that server begin to suffer. No new content can be added to the sites until some new disk space is available. In order to facilitate this process the webmaster either has to begin deleting old posts on the site in an attempt to make room for new content, (similar to housekeeping an old storage shed), or the entire hosting plan needs to be upgraded (like buying a new storage shed). It is important to note that nothing can be added to your sites when there is no disk space available, including user comments and any other data. Fortunately, most web hosting companies send out warnings via email when the disk space limitations are being approached.
