I think when companies like 37signals talk about firing clients, you might be the guy they had in mind.

Just saying... I suspect that they can do fine and provide "four nines" without your $7/month contribution.

"Four nines" is one of the reasons SLAs are pretty meaningless. That's an hour of downtime every year. One unplanned outage blows that.

Google's flagship product (search) probably breached four nines last year for some users (they had 20~40 minutes of effective downtime with that one "All sites have malware" incident) and they're much, much better than you, I, or Github will ever be.
