Good to hear. Strange, but not unusual. Normally, mismatched 
encapsulations would fail a raise of the Layer 2 transport - 
but like I said, strange :-).

How often? Like, how many times in an hour?

If you're dealing with a 3rd party, are they seeing any 
alarms that correspond to the times you see a flap? If it's 
purely an encapsulation issue, then they wouldn't. But if 
it's a problem with the infrastructure provider (which I 
suspect), they should be seeing some alarms or logging some 
donwtime.
