Verb repetition
Hi, there
In this sentence, do I need to repeat "come back" after "does" and "has"?
"At his house, whenever it rains, the power goes out. And, even after the power comes back on, it is still another few minutes until the Internet DOES too. I mean, the Internet still doesn't come back up/on for another few minutes after the power (already) HAS"
or
"At his house, whenever it rains, the power goes out. And, even after the power comes back on, it is still another few minutes until the Internet COMES BACK too. I mean, the Internet still doesn't come back up/on for another few minutes after the power (already) has COME BACK"?
Which one is better?
Thank you
