Instances dropping IE support?

A coworker was testing IE in various locations and commented that it appeared that a lot of locations have dropped IE on the public instance of webpagetest. Even IE 11 support in a lot of locations has gone.
Do you think it will come back, or are people waiting for Edge support?

A lot of locations have moved to a Linux agent so IE and Edge aren’t options. Long-term the OS is easier to keep running (and is around 1/5 the cost to run on EC2).

IE and Edge will always be available in the Dulles location but it will be hit or miss anywhere else.

Thanks, makes perfect sense! And thanks for the Dulles commitment, much appreciated!
