I also use this service in many of my scripts, please let me know when it is working again or what a new URL for this service.
We have the same issue in our environment:
during the last few days, only 1 request out of 50 was working and only for a subset of service tags.
Error message is 503 Service Unavailable
Request: POST http://188.8.131.52/services/assetservice.asmx
Status: 503 Service Unavailable
Not even getting a 503 error anymore, just "This site can't be reached".
I'll understand if Dell want to close this service, but they could have the decency to leave a message on the xserv.dell.com page with an explanation.
xserv.dell.com is brought down by Dell, as a replacement please look at http://en.community.dell.com/dell-groups/supportapisgroup/
Single Interface Support Dell’s customer support APIs (application programming interfaces) are designed to connect customers to Dell technical support systems through the customer's existing Help Desk. As IT environments become increasingly complex and diverse, Dell APIs keep technicians in the support system for which they are familiar, minimizing the need for additional training and increasing productivity by consolidating support communications and activities.
The current portfolio consists of three APIs – (1)Dispatch Request, (2)Warranty Status and (3)Support Case Management. Dispatch API allows customers to dispatch replacement parts while Warranty Status allows customers to check the status of their service tag warranties and Support Case Management allows a customer to create, view, manage and update a support case when issues arise. All of these can be conveniently done through your own Help Desk interface.
