Two Different Serps on Two Different Computers

Is MSN testing something?

[sit2510]

For quite sometimes during the past week, I'm seeing two different SERPs on [search.msn.com...] while querying at the same time on two different computers, just next to one another. They appear to differ from one another to a certain degree but not to the extremes. Has anyone notice this?

If I answer this, you have to promise to stand up for me the next time someone says we do new releases without testing them first. :-)
