Materia Data Centre Packet Loss

I've found in just the last couple of weeks that I'm experiencing packet drops in-game, which are causing everything to pause for 2-3 seconds every few minutes. This primarily happens in instances, or perhaps I just notice it there but not in the open world. It also doesn't happen every day.

I've run continuous pings in the background during affected dungeon runs, and these have shown 0 packet loss or perhaps the occasional 1 loss out of over 1000 attempts. Latency remains around 15ms with occasional spikes up to around 35. I even accidentally left the pings going for a couple of days recently, and out of 150000+ ping attempts, there were 4 packets lost.

Traceroute also shows no issues.

I'm wondering if there is some software issue that is causing this, but I've tried repairing the client, with no luck.

Is anyone else experiencing this issue lately, and have you found a way to correct it?
