Anexia-lon IPv6 down
Evening,
I've just noticed that anexia-lon IPv6 (which is my secondary 2a07:a8c1::) has been down since about 0040 this morning.
2a00:11c0:8:4::9 is not responding to pings.
Running diags on two machines currently but it probably won't complete due it hanging on the traceroutes. Will post if it completes, mtr output below.
Cheers!

Any update on this please, it's still down.

Done some more digging and testing from another network and I'm 99% sure this is the same issue as last time - LINX and Anexia have decided to stop talking to each other - which is making 2a00:11c0:8:4::9 inaccessible from AAnet.
-
Any chance you can open a ticket with Anexia and get this fixed please? I'm not bugging my ISP about this again like I did the last time because it's not their problem.
Although I imagine that it will happen again given that it's the second time recently so you probably need a more permanent fix.

We couldn’t replicate this issue on our side or any other client networks. It seems like to be an IPv6 routing issue at your ISP.
-
We (A&A, AS20712) solved this by pinging Anexia's router on LINX from our router on LINX... this would have updated the MAC.... When this happens again we'll investigate a bit deeper. But the common factor seems to be LINX and Anexia's MAC address.
-
Sorry for the delay; there was a lot of back and forth with Anexia. We have now diverted the egress traffic for this ASN so that it does not go through LINX, as their router has some issues, as mentioned above. Please let us know if this resolves the issue.

Am I correct in thinking that this is resolved now and I can re-enable the DNS?
