Thanks Alessandro, I do appreciate where you coming from however,
do you believe that during the night from 1am to 8am today my Client did any DNS changes and resolution from Management SMS's could have changed?
To be precise (and I cannot show you that unfortunately) the output from every DNS query is just fine and always was.
Persoanlly I don't think "name resolution" could be blamed for that little "glitch". I was rather under the impression that 1am isn't a good time due to some kind of maintenances in a Clould etc.
And this just happened ... tonite - 1st time - so I really wonder if that's intermittent or rather some error on SMS on my Customer's side.
Thanks anyway.
Jerry
