Instance launch time

it took 25 minutes to launch instance (boot from image) for centos 6.6 with 10G root volume. this is slow. or is it standard?
i should add the next instance creation took less than a minute. placement issue? something else?

Taking 25 minutes to launch an instance is definitely unusual. Generally boot times should be under two minutes, and most of the time quicker. I don’t know what happened in this case, but it’s possible the volume was delayed in creation or it was stuck queued to boot. If it happens again, please let our support team know!
