I'm curious if anyone else has had this issue recently too? Orcon advised me that they had made a change to my handover details to try and fix a congestion issue last month (huge download speed drops during 'peak' times). Eventually, my speed did normalise, and now my download speed is much more consistent. Strangely, my ping has been quite erratic ever since. My LFC is Enable (I'm living in CHCH).

For reference, my ping has generally been very stable at around 37ms-38ms to Sydney servers. Since this change, my ping will jump from anywhere between 37ms-38ms (my normal latency, completely fine) to upwards of 56ms-58ms. I understand this increase isn't ridiculous. However, I'm wondering what might have caused something like this? Perhaps its just coincidence in my handover being changed? I've read that any number of network changes can happen outside of an ISPs control. Time of day seems to have a slight impact; ping spikes are more common in the evening, but can still happen early hours / afternoon on weekdays. 

I have observed this latency change in World of Warcraft, Battlefield 5, Overwatch and Discord. All of which use servers hosted in Sydney (as far as I can tell). My local ping also increases too, so I don't believe this increase to necessarily be an international issue either.

The vast majority of trace routes I've performed were under test conditions (albeit a few were done when someone else was streaming Netflix). Although, on a gigabit connection, that shouldn't really cause these kind of increases.

This one is mostly normal, with a slight spike.

Different day, but this kind of increase has been more common lately.

Hopefully the formatting is okay. Sorry to be that guy, I'm just wondering if this is maybe an issue completely out of my control, or a possible network issue?

I know these issues are mostly just a 'deal with it, you can't tell the difference anyway', but I'd very much like to know if anyone else is experiencing these issues. Either way, I'd really appreciate any input / assistance :)
