[AusNOG] Sydney Routing Issues

[Travers Stark]

Yeah we are seeing some strange behaviour which started at about 4:30ish . I have not narrowed down whats going on however peering networks dont appear to be affected (at my end anyway)

There is something fishy going on at present as routes back to us from Optus which usually go Optus->Vocus->Us are going Optus->Telstra->NTT->US

Might not be related.

Tom,

Yeah this was deliberate on my part.  The issue looks to not have been replated to the Equinix MLPE and instead another peering fabric which I will not mention here as it's likely an issue between ourselves and another participant who exists on Equinix which has created the issue.

Thanks for the follow up.

Kindest Regards,

Nathan,

Looks like your sessions to the Equinix MPLE flapped, or your routes did at least:

tom at edge01.syd01<mailto:tom at edge01.syd01>> show route www.simtronic.com.au<http://www.simtronic.com.au>

inet.0: 471072 destinations, 565335 routes (471025 active, 44 holddown, 31 hidden)
+ = Active Route, - = Last Active, * = Both

223.25.112.0/24<http://223.25.112.0/24>    *[BGP/170] 00:16:00, MED 2, localpref 150, from 202.167.228.122
                      AS path: 55707 I
                    > to 202.167.228.39 via xe-0/0/1.599
                    [BGP/170] 00:15:56, MED 2, localpref 150, from 202.167.228.123
                      AS path: 55707 I
                    > to 202.167.228.39 via xe-0/0/1.599

223.25.118.0/23<http://223.25.118.0/23>
101.2.168.0/22<http://101.2.168.0/22>
223.25.112.0/23<http://223.25.112.0/23>

All flapped (were withdrawn/announced) at the same time.

however 223.25.118.0/23<http://223.25.118.0/23> was not.

Cheers,
Tom

Tom,

Hence why I asked 'To any other paths', It looks like it's an issue isolated to another peering exchange, not Equinix.  Thanks for the response.

Evening All,

Is anyone else seeing reachability issues on the Equinix MLPE or to any other paths? Twitter, SMH etc.

AFAIK, Twitter isn't on Equinix SYD. SMH is Akamaized.

What reachability issues are you seeing?

Tom.
