Same time every night AU Server lag

It was fine the first few days of the league but I think the last 2-3 days now we've been lagging as soon as it hits around 9pm AEST

Here's a WinMTR run of around 500 packets.

Is this an ISP issue? Or routing from you guys?

Edit: I should say I'm with iinet/tpg

Yeah same thing for me every night around the same time. Thinking it cold be the ddos attack they referenced yesterday but was hoping it was going to be dealt with but obviously not unfortunately

Not just you, I'm with Vodaphone and getting the same latency issues every night around 8pm or so.
