how to access all the HP-UX patch details.

We were using some perl script for download all the HP-UX patch details using the xml file ftp://ftp.itrc.hp.com/export/patches/patches.xml. But from last month onwards this file location is not accessible. Is there any location or file which is having similar kind of data which we can refer for patch details in automation ?
if its not available, then which is the link for having all the HP-UX patch details ?

Thanks in advance,
