Normal or sporadic outages?

Over the last few days, the Formal Naval Person blog (NSFW) has been experiencing a more normal pattern of traffic. To me, a normal pattern shows a great deal of continuity in traffic. There are no odd spikes or valleys. If you look at SiteMeter on higher traffic blogs, you can see what a normal pattern looks like. A return to a normal pattern makes me think that Blogger has been having ongoing problems. That seems more likely to be the problem rather than BlackLabel Ads, SiteMeter, or IndexTools, all of which run scripts.
