Not an outright ban, but I am unable to use Interactive Brokers client portal (or even signup form) using a regular internet connection. It keeps timing out, logging me out, etc.

Bizarre part is it works fine when I tether via my iPhone.

Also there seems to be growth of websites in NZ that use some sort of Cloudflare-like proxy that very often straight up blocks requests to some simple blogs. Unsure whether it's user agent, ad blocker or my IP is quite dirty, but try to open up www.pointhacks.co.nz and click thru older posts...
