Weird 'Net Twitchiness

I don't know what's causing it, but I've been having problems accessing services authenticated by Google, such as Blogger and Gmail. Around 6PM my time, the connection starts become a little wonky as it becomes evident that Japan has expanded access to broadband faster than it's expanded the infrastructure to support it. From 6PM until midnight or 1AM, the connection is not very fast, and the ISPs do their best to stop any kind of peer-to-peer filesharing, such as Winny, BitTorrent, and eDonkey.

During that time, I have issues getting logged into Blogger, for some reason, though if I'm already logged in I have no problems using the site. I had to restart my web browser around 4PM and didn't log into Blogger again until about 7PM, and it naturally failed. I was able to login around 1:30AM and now it's all good.

As far as what the problem is, I'm not certain. Only Google seems to be affected, strangely. And only if I'm trying to log in. It's weird.
