The Outer Sphere article states
"the Mobile Frontier, an ever expanding zone nearly fourteen thousand light years across at its greatest extent."
I'm probably overlooking something, but my understanding is that OA's "current date" is Y11K with an offset from our current dating system. As a result, I think that the above statement might be better as "the Mobile Frontier, an ever expanding zone which is currently somewhat less than twenty thousand light years across at its greatest extent."
Otherwise, something like 5 to 8 thousand years have disappeared somewhere
