As a courtesy, Web Services provides calendar XML data that can be consumed by IT departments on campus. This data is not intended to be used as an on request web database. Rather this data should be queried and then stored in a local IT database for day to day access.
Web Services experienced extreme abuse by web XML queries today resulting in services loss. Web Services will put together over the next few days a policy regarding the proper use of XML data. We have turned the XML processing back on but if we find that its use is resulting in service loss we will be forced to remove access.
