Dave, It shouldn't. What I've been told is that Google doesn't use crawling speed for this measure,they use visitor data (probably from toolbars and the like) to measure this. So it's how fast your pages load for visitors.
In my case, and talking of data centers, I'm hosted in a center that has traffic sharing with most of the large residential ISP's in my country. So there's like no distance. When I traceroute from my house to my host, it goes:
- my isp
- my isp in the city that has my servers
- the traffic sharing facility
- my data center
- my server.
Google apparently is also part of the traffic sharing arrangement so I'm one hop away from their crawler too - but that's apparently irrelevant.
There are other factors in making a page load fast for visitors as well.
