How many times?
If they are using exponential backup (doubling the "cool off" time for each failure) and keeping the time in seconds, that would be about 31 times. Of course, if their code was using a 32-bit variable, it might be an interesting question whether the next "fail" would wrap to a low number, while a signed/unsigned confusion could lead to requiring one to wait -48 years.
