Bing - Ping Failed? Why?

Hi, this evening i have triyed to generate a manual site map, but on the details i see that all the search engines ping are ok, but not Bing....


is it a my problem or is Bing that have problems?

Bing is pining fine for me.

It's possible there is a network related error between your server and the bing service when it ran. It may fix it self tomorrow.

Ok, thanks,
it is not fixed tomorrow must i contact the host to fix it? Bing is a very important Search engine :S

Should be possible to know the bing's IP used by the seo's site map?

I would check if is blocked on the server....

PS
Is it this:
213.254.248.187

??
