google chrome is warning me all the time the forums are not safe.

I agree with the OP, never had the issue before these regular DDoS attacks started. So either it is related to that (regardless of the above post) or SE haven't updated their security.

It's most likely coincidental. The DDoS attack is targeting the ISPs SE uses to connect their game's shards (datacentres) to the world at large by flooding them with junk connection requests that are indistinguishable from legitimate ones. It's just that the version of http that the forums use is insecure... the Lodestone and other pages use https and thus don't show the "Not secure" warning (which you can test if/when you can reach them).
