I suggest having a backup plan. I myself do also purchase isrobot cards every month for that very reason. Bots such as this usually are updated when the creator finds that their work is not working, so they are generous enough to make a release for the public use.
During the downtime, isrobot is always up to date (for the most part). It is $9 for a bot card (480 hours), I would get one that way your down time is minimized. p.s., did you guys here they are coming out with another new server on the 17th?
