How would they do that though? If you look at the details of what cause the outage, it was not a matter of free vs. paid users. Even if they added extra redundancy for paid users that they didn't give free users, that wouldn't do any good in the case of a site-wide failure, which is what they had.

For that matter, I don't think they've ever had an issue that could be isolated to affect only free users, have they?

For Outage #3 they said "After inspecting the HTTP logs, we identified a Yahoo! spider that was making thousands of requests but never waiting for responses." Spidering isn't an issue for the paid private repos since they have nothing public to index. However, the web access to private repos went down due to the spidering of the free user pages.
