Run on Sentence Question

Do I need a comma between again and so? It looks like it's a run on sentence.

Are you going to be able to give us access to Las Vegas again so we can at least jump back and forth between the servers to find files?

Largely because the passage is too complicated to be expressed in a single sentence, yes, you do need a comma between 'again…' and 'so…'

What but clarity changes if you cut the example down to 'Are you going to (anything)… so we can… find files…'?

That isn't a 'run-on…' sentence. It's a lengthy passage posing as a sentence. That the comma would at worst stand in for a conjunction doesn't change the need for one.

Will you truly consider what 'Are you going to be able to give us access to Las Vegas again so we can at least jump back and forth between the servers to find files…' might mean?

To me, that seems wholly contrived and either way, so unclear as to be nothing but confusing.
