So Microsoft has an outage in their data centre for Bing travel.  I’ve heard great amazing stories over the grapevine about this one, but anyway…
Bad Microsoft – slap on the wrist – don’t put your eggs in the same basket!

Google caches it (on 4 July) – and displays it in their search for bing – long after the Bing servers are up and operational again (it is now 10 July).

(Google result for Bing – currently)

(Bing travel is running fine now!  And has been – for the last 5 days!)

Makes you wonder if GMail (their own internal product), or CNN (a major external website), or even Microsoft.com (MS itself!) had an error whether Google search would continue to show the cached error page for 6 days.

I guess bing.com (their competitor) gets special cache rules.
