Is your #network fragile?

Was thinkng this morning about comments ive gotten sometimes from customers about not wanting to risk their network with a second vendor.

That there was risk in doing so.

Here's my question im going to start asking back.  If there is risk...Is that because your network is fragile?  Why do you have a solution from a vendor that is so fragile..It cant interop?  The risk then isnt with having two vendors...Its with the one you have.
