!!?

You really think that 14ms difference puts you at a "distinct disadvantage". Try http://reflextest.net/reaction/color.htm. Human reaction time to visual stimulae is about 190ms meaning the time it takes you to click your mouse puts you at more of a disadvantage than your connection's latency
190ms? Even the RTA says a second to be safe. Mine was .40 (and that was my worst).

Anyway, I also have some slow browsing issues, not sure if this is in any way related to that...still happy to help troubleshoot however I can.

The explanation from Optus is:

"The identified increase re latency in New Lambton is not at present diagnosed as congestion but a direct result of the dynamic SDH network. The redundant SDH network from Sydney to Newcastle if switched (due to a cable cut or other work) moves to the redundant path ie via Brisbane back on the inland route to Sydney.

We run the SDH network in non-revertive mode because intermittent faults cause substantial customer outages if the network switches to a faulty path, cable cut or card failure.

There is a network ticket raised to revert the network."

Awesome, great to finally get a response on this!

As to the '14ms doesn't make any difference' comment... It's hard to explain why or how such an insignificant amount of time makes any difference in gaming, but it definitely does - it might not be your initial response, but adding that 14ms onto the refiring of your gun or stabbing your knife can quite often be the difference between life or death

The issue appears resolved again for me.
Is anyone else now still experiencing the issue?

Thread closed.

It is pointless to revive old threads and force other readers to read through pointless/out of date information.

The Optus network path issues are NOT capable of being addressed by Exetel and we don't need to have several identical threads pointing out that the Optus hub in (Newcastle in this case) has reverted to it's alternate path.

Optus is aware of the issue and when they figure out a way of fixing their current methodology they will undoubtedly do so.

In the mean time dozens of posts saying the same thing here are not going to achieve anything.
