The Verizon ads are gone, and most of my control is back.
doubleclick.com has had a long reputation of oversubscribing its service, going back to at least 1999. I know of at least a dozen websites that kicked them off their pages in the span of 2000 to 2002, because they were chronically causing load delays and load failures.
Yup, I know there used to be problems with DoubleClick a couple of years ago, but those have since been resolved in the latest year or so. In any case, it appears the Verizon ads weren't being served by DoubleClick anyways. No matter how much you want to blame it on DBCLK, they're not the problem, I promise you.
