This started out of nowhere yesterday morning, nothing changed on my end to trigger it. Similar results to everything I ping/tracert. Up until yesterday it'd always be 18-22ms.
Anyone else experiencing the same thing?

I'm seeing something similar - except that I'm normally at around 30ms and it's gone up to around 60ms minimum since yesterday.

Pinging my default gateway:

It looks like another case of North Coast/Newcastle ping times. I just did one from northern Sydney as follows:

I can't recall my average Ping.
If I connect as ADSL1 g.dmt speed my ping is 52, or about 10 ms higher than BisPlus

So vert02 - did your latency return to normal? Did you raise a trouble ticket?

I'm just curious as to whether your experience has been different to mine...

It's still elevated :(. I literally just submitted a support ticket about 5 minutes ago and referenced it to this thread. Hopefully we can get a resolution.

It does appear as if there are issues isolated to north areas of NSW, here's the results of testing with low traffic:
--- 220.233.1.149 ping statistics ---
28 packets transmitted, 28 received, 0% packet loss, time 27035ms
rtt min/avg/max/mdev = 43.108/110.205/169.503/33.154 ms


And it seems related to Optus based services in the Newcastle / Central Coast region. I'll see what response I get from Optus.

Actually, I checked a monitor I setup some time ago - it's started 29th May.

Interesting. Are those loss values abnormal? I've been noticing 3-4% packetloss spikes frequently as it gets to peak hour and during the start of offpeak.

They are likely related to the connection usage, the increase in latency is still evident though.

Thanks Jason - much appreciated :)

My parents have an Exetel ADSL1 connection on the same exchange and aren't seeing any increased latency so I assume it is something related to the Optus ADSL2 network...

Did Optus recently expand their bandwidth?

46ms ping... I don't think I have ever seen that fast from my 8mbit ADSL 1, although I do live in Tasmania so my data has to travel through 3 trunked 56k dial up links which connect Tasmania to the mainland :P

My ping has gone from about 60-80ms to about 600-800ms since the weekend.

At the moment it has actually become usable, its down to around 100ms.

Seems to be back to normal as of this morning.

Thanks Jason. :)

It hasn't changed...

No update from Optus yet.

Same exchange, same improvement. 20ms better today.

Uh... maybe it was exetel.com.au which is the cause here.. Heh.. doh?
Maybe we all need a standard server list to ping.
