In case you were wondering, the optimal time to roll out new network software is Tuesday some time around 00:00 UTC to 02:00 UTC.
As seen on the namedroppers list:
I’ve always found it best to roll out changes on Tuesday, as it gives plenty of customer feedback time during the week. Mondays are often consumed with catching up on any operational problems over the weekend. Tuesday is better. 02:00 UTC is my favorite, although anytime after 00:00 UTC usually works OK.
