Welcome to the Q&A Forum

I use Pingdom as well. Good to have choices!

Likewise to you Simon, thanks a lot for the advice!

Hi Jimmy, I do not have any hard data to refute what you are experiencing; however, I will share it is highly likely the spike is related to other factors and the TLD being .org or .com is completely unrelated. It would be an exceptionally major change for Google to change how they value TLDs. Such a change would be front page news on all the SEO sites.
