How long does AWS take to approve P2 limit increase request

I sent a request in for 1 limit increase on Sunday, got a reply a few hours later that they will service it but need to get approval from Service dept. Its been 2 business days and no word. Is that usual?

Yes, around 48 hours, but you can (should) bug them to keep attention to the ticket.

Thanks, got it last night!

Not much time. At max 48 hours.

Just a recent data point…

In the last week or so I requested a P2 limit increase as described in the “AWS Deep Learning setup” video and last paragraph of:

FWIW, it took more than 12 hours, but less than 24.
