Is it just me or has the JavaScript runtime distribution have been way off?

Last year I usually fall within the runtime normal distribution, if I submitted a solution approximately within the fastest time complexity.
But for the last month, I am falling way off the runtime normal distribution even if I submit a problem that has the best current known time complexity, I will still be way to the right of the normal distribution with someone that submitted a problem before with a exponentially worse time complexity.

I know that for some problems the time complexity does not impact the runtime, since to see drastic results you will need a larger input length which will be too expensive to have.

I was just wondering if others have had the same problem as me or is just my internet speed or recent server change.
