I read thru some of these posts and you would think the world ended. Can i return any Windows software it seems like it wasn't tested enough. The other word for poo happens, you can only hope to reduce as much of that before it goes into production.

DonGould: ? Perhaps you and Salty would like to educate us all on just how many change requests are pushed though daily.?


The VAS operations team are typically making changes of one sort or another 4 times a week, ie Monday night to Thursday night. Major releases are normally launched on a Monday so that adds Sunday night deployments on those weeks too.

There are three of them to handle that as well as on-call.

I recently got an assistant design person, before that it was just me to handle SMS, MMS, WAP, Voicemail, and the IN. The new girl is taking over a project aiming to reduce some of our SMS problems, and I will probably give her MMS to look after as well. 90% of my time is spent dealing with the IN as it is critical to every product or service we offer and so it requires a great deal of care and feeding.

In terms of testing, Don is right when he says that NZers are not willing to pay what it would cost for us to do full network simulated loads. Those machines cost in the order if several hundred thousand dollars to hire for a month. Generally we are limited to functional testing. Only vendors can afford load tests. And unfortunately the vendor still has not managed to reproduce the issue of the other night. Needless to say we will not be allowing it back into prod just for the collection of more debug.

It's fair to say that's probably the most spectacular fail I've ever had the misfortune to have my name on.

"Intelligent Network."

It handles rating & charging, call flows, business process logic... If a decision is made about a service you're using, the IN made it. All your 'stuff' - cash, value packs etc - lives in the IN. There is nothing you can do on 2degrees that wasn't mediated by the IN.

Salt thanks for some great feed back.

For those of us not directly in the game, I always consider it really cool to get this kind of candit comment.

I agree with dothack, some times stuff does just break.

One message I take from Salty is that if you want to sleep all night then put your phone on silent and or set up ring groups/profile/what ever your vendor calls it... so that your phone only rings based on calls/texts from people who should be contacting you at that time - ie your emergency phone list.

Personally I'd like to see all scheduled work published to a mailing list so that everyone can manage and plan their existence.

I also wonder if this space is getting more and more complex and expensive and it's going to get to a point where it's not practical/possible/affordable to have a local team with the required resources with the way the current technology is being deployed?

Why did XT only have 1 thingo in Christchurch that broke and took out half the country? I know the basic answer is because the entire country only actually needs 2 'thingos' to work.

I wonder the same thing about the ERX thingo that TelstraClear has that died when they put that in and took 5 days to reload all the customers.

Are we building systems the wrong way? I'm not saying we are.... I'm just wondering if these big centralized systems are the best solution or if we should have more smaller systems?

Salty, frankly if this is your darkest hour so far in .nz telcom's, then you're either much younger than I am (41) or doing very well! :)

I'm 35. :) I've certainly had much *bigger* faults or upgrade failures than this, but that was the most widely publicized so far...

Now that is a whole other issue...

It's also a very interesting issue.

25 years ago no one outside of Christchurch knew much when the CBD phone network went off line for 5 hours at a time regularly.

Today tech news sites around the world are able to pick it up and publish the details extremely quickly.

It's also a very interesting issue for vendors....

It would take some effort to persuade me to choose a number of vendors based on their track record with telcos in our region.  I wonder if this technology is going to get harder and harder for them to sell?

Oh, and another couple of thoughts... I think I picked this thread up because you posted in it. I wonder who picked it up because I posted in it? Or who read it because I posted... or you posted or did they consider threads that Steve's interested in of importance?

It's not just that it hits a news site any more. We're looking at a whole new kind of media now.

freitasm: He got suspended because of the language used, not because of the question.

Thank God, every time I read his posts I get the feeling he has a major, major, major chip on his shoulder over telco companies. I was quite dismayed when he made John leave a few months ago.
