Why are you reading this? And how did you get here? All are reasonable questions, as is the following:

  • Which mechanism is quickest for trigger a crawl to a recently-registered .co.uk domain?

The only way to answer that question, of course, is to try different methods and see which one emerges as the victor. And that's what this post is.

Also note: are there separate dates for first discovery and for evaluation? Does this post include a time machine?
