Telecom NZ would like to advise that there will be planned work undertaken on the Telecom BroadBand HTTP Cache farm starting on Thursday the 22nd of July.

The planned work has an extended window of 7 days.
If the date of the work changes there will be an update sent out.

This work is to expand the cache farm to include more of our customer base.
We expect this work to improve the browsing experience for customers passing through the cache farm.

There should be little to no impact on your browsing experience during this change, however if you do experience a loss of international browsing then please contact the Broadband Helpdesk on:

    adsl_helpdesk@xtra.co.nz

If you would like to talk to the Helpdesk then please phone:

    0800 22 55 98


Details
=======
Planned Start Date:     22nd July 2010 08:00
Planned Finish Date:    28th July 2010 23:59
Expected Impact:        Minimal to None

If you have any specific questions about this work then please feel free to post the questions on this mailing list/forum and as time allows they will be answered.

NB. Please note that the service is only in place for Telecom Broadband Customers and "International" in this case is based on the international routing tables, as such some domestic sites may appear to Telecom as international content.

Paul

Hi Paul, could you please explain exactly what a cache farm is?! In what ways will the browsing experience for people passing through this cache farm be improved?

Hi Corksta,

I can talk in generics about what a cache farm is and what benefits you expect to get from caching HTTP.

A cache farm is a collection of machines that performs a particular common function across all members of that farm, in this case HTTP Caching.
Load is generally distributed to the member of the farm by some sort of content switch that can operate at or above layer 4.

The normal things that any ISP wants to see from such an activity are increased speed of delivery to the client browser (better perceived browsing experience) and some reduction in upstream capacity use.

I cant be specific of course around our implementation so please forgive me if this is too vague an answer, so i hope this answers your question.

Regards

Paul

Thanks Paul, I had a vague idea that a cache farm was something along those lines, so your reply cleared that up for me.

Roll on the browsing improvements!

Will you make an announcement back here when it's done?

This maintenance window has now closed.

We are likely to open a new window in the coming week and I will post that here again.

Question for a mod:
Is it possible to perhaps have these notices sticky for the period of the planned work?

The email address you posted doesn't work.

adsl_helpdesk@xtra.co.nz

I am having trouble viewing some websites through my Telecom broadband connection. The content is old and cached, yet when I view on another ISP, the content is current. Is this related? I have cleared my browser cache, but it makes no difference, the pages loading through telecom broadband are still cached. This has been going on for a week or so.

I am sorry about the email address its something i was provided but I should have tested it before posting it online.

Have you called the helpdesk?

Are you able to specify what sites, and what portions of the site are stale?
This can and does happen with HTTP caching its something that is common among most caching solutions.

If you PM me the sites i can investigate and see what can be done.

Regards

Paul

Hi Paul,

The email address may be adsl_helpdesk@telecom.co.nz rather than using the xtra domain.

It's the one I occasionally use if I have queries about my connection or details on the telecom website.

Oldhat is quite right.
Sorry for the long delay in the update, this week has just vanished on me.

Apologies
