I'm with 2degrees fiber, a happy customer.
My IP address is dynamic, but usually changes fairly rarely - every few months. It's changed a couple of times recently, which is slightly annoying as I have a couple of services that are dependent on my IP address. It's not a huge problem to change them, just a minor annoyance.
Here's the relevant router logs.
26.10.18 04:43:50 Internet connection established successfully. IP address: (new IP allocated - removed)
26.10.18 04:43:31 PPPoE error: Timeout. [3 messages since 26.10.18 04:43:03]

26.10.18 04:39:31 Internet connection cleared.
23.10.18 12:46:17 Internet connection established successfully. IP address: (new IP allocated - removed)
I'm just curious if anyone else found this, if it's just me, there was maintenance going on, etc. If it happens every few days I'll either want to automate updating my IP in a couple of places or find a way to get a more static IP.
