Kumo.com is now registered under Microsoft and the name servers are now under SEARCH.LIVE.COM. Going to Kumo.com takes me to a page that says I do not have permission, but takes Microsoft employees to a special internal site.
We heard Microsoft might be rebranding Live Search, once again, to a new brand. I never would have imagined it would be Kumo, which means “cloud” or “spider” in Japanese. I certainly hope they don’t go this route, it just doesn’t seem like this new name would help them in any way.
You can see more discussion around Kumo, as a new brand name for Live Search, at Techmeme.
