Happening every night for a few weeks now.

Starts around 6-7pm, usually back to normal 2-3 hours later. But particular bad tonight.

Cloudflare DNS seems unaffected (NZ traffic), seems to be mostly Aussie (and Singapore?) traffic.

Edit: Latency also goes back to normal (well, even lower than normal NowNZ), when I connect to a NZ VPN.

Google ping;

Google DNS 8.8.8.8
