All requests on my sites look normal today -- and that's actually a new thing, because prior to last month, Twiceler apparently did not understand multi-user-agent policy records in robots.txt, and as a result didn't crawl the sites. That's changed now, and they're crawling away (at a normal rate).

Combined with Lord Majestic's speculation above and the "ramp" hosts with no UA, it wouldn't surprise me if they're preparing to roll out a new index some time soon.
