[AusNOG] Carrier aggregation port redundancy

[paul+ausnog at oxygennetworks.com.au]

Thanks for the reply Nathan, Telstra will do it now within the same DC, but that's not good enough redundancy in my books so I'm keen to understand what other options are around.
 
Having come from a banking DR background a while back I know how critical different DC redundancy is, and usually when a carrier has an issue it will take out more than one piece of gear or fibre, they really need to offer some options on this I reckon.

Paul

Hey Mate,
 
Layer 3 redundancy everyone will do without to much pushing, Layer 2 no one will.


If customers want Layer 2 redundancy they need EVC's to multiple DC's.

HI all, just wondering what experience people have had with negotiating aggregation port redundancy/failover at different datacentres within the same state for major carriers ?
 
We are looking at implementing some geographic redundancy for our layer 2 connections which are handed off on an aggregation port in one datacentre so that we have a second aggregation port in another datacentre should the carrier or ourselves experience a major failure like an exchange switch or something.
 
We have had 2 or 3 failures over the last couple of years which luckily were on weekends and the impact was lower than normal, however the carrier does not have any interest in providing such an option across datacentres, they will do it within the one datacentre as long as you pay the full install and MRC on the second redundant port, but I can't get them to do anything in separate locations.
 
Am I the only one who thinks that having geographic redundancy for such services is important ?
They don't seem to think it's an issue and are saying that they won't do it but I would really like to have it for obvious reasons and am not sure if I should keep pushing or not.
 
I'm interested in other peoples experience in this area please.
 
Regards
Paul
