The Internet arm of AOL Time Warner provides a service called AOL Hometown pages, where AOL members and non-members can host personal Web sites.
Over the past few weeks the company has been upgrading its servers and storage capacity to keep pace with demand brought on by new users, according to Nicholas Graham, an AOL spokesman. Some users who have set up pages through AOL have been unable to update their sites because of glitches in the upgrade process.
"During this time some members may have experienced some intermittent and sporadic outages," Graham said. The company is in the process of patching the problems, and some errors may persist.
The Hometown pages service has roughly 10 million users and hosts about 14 million pages, Graham said. He said the glitches resulting from the upgrade affected only a small number of users.
"Many members have had no trouble accessing, transferring or uploading materials to their Hometown pages," Graham said.
