Can someone explain? (Are all the reds failures? Is it all physical damage to cables, or some other cause?)

This whole page is an exercise in confusing UX.

Left has "Active" in red because it's "Active Incident" not the cable is "Active" but at first glance "Active" makes it seem like the cable is operational.

The title is a bit misleading. We have internet here. We also have several cables currently damaged.

Sorry, should have said "Current Cable Outage" instead.

Exactly. It's not like Taiwan is the only place with cables damaged. Australia used to be worse.

I can remember when 1 cable outage cause all caused all of the east coast of Aus to lose internet access

The alerts icon (triangle with a ! in it) shows a text list of the outages. There are many active; only one happened recently. They seem spaced out from each other, not indicative of a burst of Chinese naval activity.

It is not a burst but a consistent sabotage action happening in the background [1]. To make the matter worse, those vessels that commit the crime will be merchant ship flying flags of convenience. [2]

Extremely likely.
