This will do nothing, as it's not their decision to make. I'm occasionally in the position to be buying services from commodity providers. If your service goes down and I start shopping around, the question is not "Will I ditch you for someone who can deliver?", it's "Which one will I move to?".

You might as well try to be in the running with some well-timed advertising. I'm sure you're emotionally invested in being a nice guy to the folks in the booth next to you, but as your customer I can assure you I'd rather see you fight.
