Some users are seeing a new feature on Bing, a feature that lets you test how fast your internet connect speed is. All you have to do is go to Bing and search for [speed test] or [internet speed test], and you might see it yourself.
I personally cannot replicate this, but Windows Central was one of the first to spot this.
Here is a screen shot from Venture Beat:
Microsoft told VentureBeat, “We’re always testing new experiences for Bing, which includes the Speed Test experience,” adding “We have nothing further to share at this time.”
