Trying to think logically and something about this does not look normal to me!

In 2015 google had a massives drop in crawls made at archive.org.

February and September had only 1 and July had 2.

What is even more suspicious is what happened in those 3 months of 2015 in particular.

In February 2015

China's foreign minister pushes Iran on nuclear deal

Clapper’s annual report does not mention Iran as a terror threat, soft peddling their bad deeds..

Boris Nemtysov is killed on a bridge in Moscow.

Kasperskey Labs discovers the NSA has the ability to hide spying software in hard drives.

July 2015

On July 14th Iran agreed to the historic Nuclear deal.

September 2015

Democrats blocked republican attempts to thwart the nuclear deal.

Twice! on both the 10th and 15th

Google Trends for 2015 shows a massive spike in interest in those particular months.

Who was watching and had the most interest?

The Washington D.C area and also cities where many members of congress live had the highest ranking.

Is it a coincidence that the 3 months with the highest (public? or governemental) interest in the Nuclear Deal had virtually no archive.org crawls?

If I wanted to make sure nobody would see any shady things I did in that time period how could I do that?

Is this normal?
