"My Power Link connection was down from about 10 PM until 3AM last night, and this morning I notice I'm on a completely different subnet, 67.20.xx.xxx instead of 24.58.xx.xxx like before the outage. Are they doing some maintenance work?"
Adelphia CMTSs are frequently assigned multiple, non-contiguous blocks of IP addresses, so an IP address and/or IP subnet change isn't anything unusual after an outage or upgrade.
IP changes can happen during outages that are longer than your IP lease time or when a large number of people go offline, but it doesn't specifically mean any network upgrades or changes were done. Such address changes are totally dependent on how many modems are offline and length of the outage vs. size of the assigned subnets and the IP address lease time left. The larger and/or longer the outage, the higher the chances that your subnet and IP address will change.
Adelphia's change management window is during the "silent" off-peak hours. Normally 1:00am to 5:00am. An outage that starts at 10:00pm is an unscheduled one.
