MrVM AU SYD IPv6 Issues

Hello,

Is anyone else noticing IPv6 issues with MrVM's AU (Sydney) location?

I have mostly intermittent connectivity from multiple locations (mainly in Europe) and thought I'd just shout out and see if anyone else is noticing issues.

Thanks.

Re: MrVM AU SYD IPv6 Issues

Can you show a traceroute when there is an issue and advise where it is stopping (in both directions if possible)?

TIA

Re: MrVM AU SYD IPv6 Issues

@oliau - thank you for the quick reply.

I'll provide a mtr dump soon.

What I've noticed so far is that there's loss at 2406:d500:6:235::1 which is the next hop from 2406:d500:6:beef::2 (which is presumably the host node for MrVM).

Re: MrVM AU SYD IPv6 Issues

Here's another from MrVM (Bulgaria) and this appears to be caused by a Telstra issue (primarily) but there's still loss at the same 2406:d500:6:235::1 IPv6/point.

Also, just in case it helps, I'm not noticing any loss on outbound mtr's from the AU-SYD node.

Thanks in advance.

Re: MrVM AU SYD IPv6 Issues

I’ve noticed this as well from random places, never at the same time though.

Re: MrVM AU SYD IPv6 Issues

Tagging @oliau just to ask if there's any update on this or at least thoughts on why this is happening? I'm still seeing this pretty consistently and thought I'd check.

Thanks in advance.
