Certainly, but I would say that there are very few Internet startups that cater to a single (or even a few) geographical locations. Your numbers currently indicate quality of service for customers in the same hosting block as Amazon EC2. If you have enough monitors and spread them out well (which shouldn't be too hard, since you could just sign up for Perl/PHP enabled hosting accounts in different locations), you can still diagnose where the slow geographical regions are. In short, having more data can only give you a more accurate picture, depending on how you analyze it.
