ADSL has just gone down (no PPP) for 2 Xnet subscribers, one in Pukekohe, one in Onehunga. Anyone else?

Has anyone rung the helpdesk? I won't, I'm sure they will know about it.

How do you find the Draytek's Scott ?

Uea was down her in Gisb but what was annoying was none of their phone lines were working either ... ended up getting a Fax through.

Haha yeah, it wasn't a small outage and it seems the phones couldn't keep up with demand :p. Everything should be on its way back now.

Nicely done btw Scott :D.

Like it very much - very stable, awesome line stats given distance from exchange, some very nice features, well supported through firmware updates, friendly helpful support desk, all good!!

Great to see an explanation of the problem (on the XNet status page). Thanks for telling people what happened.

You can never have enough Volvos!

This has happened quite a lot in the last 2 months, not for as long as this, usually only for a few minutes, instead of the 20-30 odd that it was today.

It's causing a lot of pain for our customers, as everything goes down (internet, phones, fax) etc. Is there a root cause, when do you expect this issue to be resolved long term?

Tyler - Parnell Geek - iPhone 3G - Lenovo X301 - Kaseya - Great Western Steak House, these are some of my favourite things.

Yup, great to get an explanation. But as already said - it was quite alarming to find the helpdesk unreachable during the outage.

Red Jungle: we make fantastic software

Hi,

As I've mentioned to Xnet in the past, outages due to single equipment failures are just not acceptable in this day and age. There are numerous techniques to avoid this, from network redundancy, to redundant hardware, to in-chassis redundant supervisors, and even redundany software.

I happen to work for one of the equipment suppliers, and know what is available, and am a bit shocked when a major ISP like Xnet suffers outages such as this.

The PPP and AAA servers must be redundant to the point of physical location and network paths, as well as having onboard hardware and software redundancy. They are the most important items of equipment in the network (given that they are also tied into the billing systems ;).

Forget the international bandwidth - get some high availability happening.

Start off with creating an availability model of your network, tieing in paths, MTBF and MTTR of all equipment, contact your equipment providers for their figures, and also monitor your own network and collect your own real figures to feed back into the model.

Cheers, Ed.
