No. I don't not believe they've done this. They don't peer easily or often and peering with local partners is not something most people want to do, even Google. It takes trust on the part of the local service provider, which Google hasn't built as Google is often a direct competitor to their local products. Peering at the ISP level is really hard because it's all relationship management. Google couldn't manage their own fiber and built up a good deal of animosity with other networks in doing so, especially in the US.
Interesting information. There's definitely a bit of marketing going on there, but it seems that they have at least some peering. Without concrete public evidence otherwise I'll concede that Google must have great peering.
From a network administrator's point of view, they're an absolute joy to work with too.
If you're share any IXes with them at all, they'll peer with you. Private / appliance based peering has additional requirements, but that's par for course.
