I live in the North Porirua area and had 100/20 UFB installed in February, since then I have perceived that I get a lot of mini outages, more than with VDSL using same ISP - a web site does not load, I find I cannot ping external IP addresses for a short period.
I have a smallwall router running on an ALIX board directly connected to the ONT, so smallwall does the PPPoE login. The ALIX board may be a bit underpowered, but I still get a measured 86Mb/s with ALIX CPU running at 90%.
So I have looked through my router logs and find many PPPoE logins preceded by WAN interface link DOWN lines. Many of the outages are a few minutes and are pretty annoying and have occurred several times on some days.
Here is a (sanitised) list for Sept:

Is this common?
Is it due to an underpowered router/firewall (unlikely)?
Is it unique to my ISP ?
Is it some other reason?
