What's happening with vocus these days? I was connected to work and suddenly by remote desktop got very slow.

I am seeing very high latency to all IPs national or international. I checked with my colleague also with Vocus group and his is fine. Can anyone else on Vocus chip in to this?

I am seeing a significant jump in latency after my GW (ignore my double Nat'd router over wifi). Usually the next hop is default-rdns.vocus.co.nz which is missing. Is it congestion or maintenance (ON A FRIDAY EVENING lol)

Not on Vocus retail but evidently provider uses them for backhaul as per the Voyager thread the other day and I am seeing intermittent bouts of high packet loss for a minute or two and stalled TCP connections.

In the last half hour connections dropped around 18:32 and again 18:47.

I'm in Auckland. Interesting that it was fine for some people in Auckland.

While it is fine now but it definitely lasted for more than 1.5 hours. My traceroute hops have returned to normal along with ping responses. Guess will never know now coz not many people were involved.

Im back with another post of struggling to wfh on Slingshot.

Is anyone else yet again feeling the lag?

I tracerout'd to my work gateway (local NZ) as well and it's same 1000 ms+ latency.

might be something up with Slingshot or your connection - all good here on Orcon [vocus]

could be worth logging a fault with them if you haven't already :)

Cool. Thanks for your reply. Can I ask though if you are Auckland based by any chance?

Weird that again its only affecting some customers only. Will probably need to check with the landlord to call them as I am not authorized on their account

Latency increase between hops 4 and 5 seem to be at the off-net network boundary so perhaps something upstream with your IP and routing.

Maybe one for @Sounddude ?

You say all your testing is on WLAN due to your network set up. I have seen weirdness in the past with some IP packets which come in from the public Internet (i.e. further on upstream/off-net hops in a traceroute) being non zero DSCP marked and causing issues with WLAN equipment as traffic passing through to the WLAN interface get mapped into WMM queues based on IP DSCP value and the AP and client not playing nice. The solution was to get the CPE router to mark DSCP zero on all packets coming in from the WAN side. I would say this is rare but edge case I have come across before.

Thanks all. I had to go to work as how laggy it had started to be. Came back home and it was allgood so can't tell when and how it got sorted.

This is a very interesting scenario that I didn't know was the case. I all together ruled out my router's uplink via wifi to be an issue as my mtr test showed ping to my router with average less than 3 ms and also was standard for second and third hop until it went off vocus' network.
