I have FiOS in the Seattle area, and I'm not seeing any of the problems that you're seeing. I have ~7 ms ping times to servers in Seattle, so the link itself has very low latency. What kind of ping times do you see to 18.104.22.168? That should be in Boston and well-connected. If you see > 20ms, then your router is probably flaky, otherwise it's probably DNS. Just swap your default DNS server for something else, or run your own caching DNS server, if you have a spare box sitting around. I would *not* recommend OpenDNS--they scare me. They've been known to return their *own* addresses to DNS queries for search engines, and then proxy all of your searches through their own servers, presumably logging all of your searches. Who knows what else they're doing behind the scenes.
