High Ping + Extreme lag spikes

Noticed Yesterday I was getting bad Lag spikes in game so checked my ping and it is sitting at 78-80, it usually sits at 26-28 i'm connecting from nz to the materia data centre has anyone else had any issue lately as i've checked everything on my end and even called my isp and they dont detect any issues, as far as i can tell nothing has changed on my end and i'm not the only person in my FC that is experiencing these issues

edit - when i log into the game i'm at my usual 26-28ping untill about half way thru any dungeon i run then the lag spikes starts and my ping comes back down and locks in around 78 with lots of clipping gcd

suffering the same problem on raids :/
