Anyone with first had experience?

Seems to have been rather minor in nature.

I expect that the communications links between Brisbane airport and the Virgin Data Centre were down.

It is normally caused by a back-hoe (digging up the cable) or a problem at an exchange.

I expect Virgin does not have backup links.

My flight QF508 had to sit on the taxiway for about 20min whilst waiting for a gate to become available. Nothing too major though .

Virgin most certainly do have redundant links...

[Michael Mak]

The link seems to suggest that only Qantas was effected by the blackout.

From Experience some company's definition of redundant links is not quote redundant.

[Greg Hyde]

Link redundancy can be done by two separate links (cables) but it doesn't account for infrastructure redundancy. ie: Same physical xchange or two cables laying in the same pit one metre apart.

The only way to guarentee redundancy is to track every link through every hop and every bit of physical infrastructure.

Done this for clients, costs more but 100% redundant.
