Yahoo Showing different results from different IPs

Has anyone seen similar results?

[werty]

I ran some reports for a client this last week and things were looking great. I send it over to the client and he cannot see his site in the SERPS. Sure enough I check from the office and he is nowhere to be found.

I decide to run the reports again and he is still showing up there. We do some testing from other IPs and it is a mix of SERPS...

Is this normal? Does Yahoo! Dance?

Does Yahoo! Dance?

I'm beginning to think so. Starting two days ago I've been seeing very different results (only slightly better, quality-wise, but then, my sites are doing a lot better so I'm happy)

Doesn't Yahoo periodically test new layouts in different ip's? It wouldn't be far fetched for them to a/b serps.

Yes, Yahoo dances. Our results are coming on the first page on certain days, totally gone on other days.

Is there any way to see this like in google and if we are lucky some of those sites where only the index site is indexed will get back fully
