Do you have Faster Broadband yet?

Now Faster (Fibre to the Cabinet) Broadband is available to more and more users in the Isle of Purbeck, we though we’d run a little poll to see if you have upgraded yet.

Have you upgraded to Faster (super fast) Broadband?

Intermittent, fluctuating and very slow broadband (again!)

The old fluctuating and very slow broadband problems appear to have returned to users in Corfe Castle, Church Knowle, Kimmeridge and parts of Langton. It looks like anybody who broadband connects to the Corfe Castle exchange.

We have reports of very slow speeds from TalkTalk, BT and Utility Warehouse (which is usually just re-packaged TalkTalk) .

We believe the problems are related to line and exchange upgrades between Corfe Castle and Swanage (Swanage will be getting Fibre to the Cabinet and Fibre to the House soon).
We have no proof that this is indeed the cause of the problems, but a support staff mentioned it when somebody reported problems recently.

What should you do if you have slow or no broadband?
Reporting the problem to your Broadband supplier (if it happens intermittently then report it each time it happens). Even if they say there’s no reported problems, ask them to make a note on your account (and check the note is there the next time you call). It will help them track issues if there turns out there is a problem.

Broadband Problems 3rd November 2014

There appears to be a number of issues this morning across the Isle of Purbeck. BT and other Internet suppliers appear to be aware of the problems.

We suspect the issues are due to the very large amount of rain we have had overnight.

If you have no internet, first try powering everything off and back on again (i.e. your broadband router, computer/laptop, tablet and phone).

If you still have problems then call your broadband supplier and report the problem.

Broadband problems 3rd January 2013

BT have confirmed there is/was a problem with broadband that has affected the 01929 dialling code.

The problem should be resolved by 6.25. If you are still having problems, try restarting (power off/on) your modem/router.

Broadband Problem in the Reading and Surrounding areas

Date & Time: Thu 03/01/2013 at 04:48
Estimated time to resolve: 03/01/13 06:25

We know that some of our customers in the Reading and Surrounding areas are having trouble with their broadband connection at the moment.

Loss of Service Worth Matravers and Corfe Castle (Again)

There is another MSO (Major Service Outage) affecting broadband users who connect to the Worth Matravers and Corfe Castle exchange(s). It sounds like there is another hardware fault, possible similar to the fault last month on the 9th July Degraded Broadband Service.

Planned Engineering Work 17th July 2012

There is planned engineering work scheduled for the 17th July 2012. In theory it will not affect users, but if you discover you have no internet access after the work, first restart (turn off/on or unplug) your Router. Contact your ISP if you continue to have problems.

Broadband Outage 29 March 2012

There was a blip in the night (00.30am — 02.30am approx) where some users had no broadband (this appears to be nation wide).

My ISP confirmed BT Wholesale had an outage over night and several other ISPs (internet service providers) have also reported customers with no service.

If you were affected or still have no broadband, try restarting your router/modem, if that doesn’t work, contact your ISP and report the problem.

Interleaving Broadband in Church Knowle and Kimmeridge

We are hearing from more and more users who are experiencing very slow Broadband, particularly users who connect to the Corfe Castle exchange — we have had reports from PlusNet, Mad as a Fish and Virgin users in Church Knowle, Kimmeridge and Harmans Cross — they’re at least 2+ miles away from the Corfe Castle Exchange, and have also reported random noise on their telephone lines.

A helpful support person confirmed that they have had to turn on ‘Interleaving’, which appears to help, but there are several drawbacks to using this.

What is Interleaving?

Interleaving is a form of error correction that can help reduce the number of ‘errors’ on a line. This will be activated by default on new broadband services and where a fault has previously been reported. It helps to stabilise a line that might otherwise suffer frequent disconnections. One drawback of interleaving is that it can increase ping times, which may cause problems for people that play online games. Whilst we’d recommend against it, if it is switched on, interleaving can be turned off if you ask us.

Traditionally adsl used what is known as “FAST” method for transmitting data.
MaxDSL & LLU can make use of a technology called Interleaving to help maintain the tolerance against noise on longer length lines.

If during transit more than a certain amount of data has been lost then the data cannot be correctly decoded by your router. Short bursts of noise on the line can cause these data packets to become corrupt and the modem has to re-request data which in turn can slow down the overall rate at which data is transmitted.

Interleaving is a method of taking data packets, chopping them up into smaller bits and then rearranging them so that once contiguous data is now spaced further apart into a non continuous stream. Data packets are re-assembled by your modem.

If your line is particularly susceptible to bursts of noise then interleaving should improve your adsl experience simply because if you lose a whole batch of data then this could cause your modem to loose sync with the exchange.

By now you may be asking if interleaving is so good, then why isn’t it used by default?
The answer to that is that it can also have a downside – chopping up, rearranging and decoding of the data adds a small amount of additional time it takes for data transmission. Forward Error Correction will also add to the delay, since the check bytes will take additional transmission time.

BT state that interleaving can increase latency by an additional 20-40ms. Whilst this will not be noticeable to the vast majority of users, ardent gamers are the ones most likely to complain about additional latency and therefore prefer a slower synch speed than higher latency.

It should also be pointed out that whilst BTw state that applying interleaving shouldn’t reduce your line speed, it does reduce the maximum line rate achievable from 8128kbps to 7616kbps due to the additional overhead required for check bytes.

We would be interested to hear from anybody who is experiencing very slow Broadband in Purbeck. We would also be interested to hear what ISPs are saying is causing the problem(s) and how they are fixing them.

Note: Remember to turn your Router off/on and check all cabling before calling your ISP, you can guarantee they will ask you to do this first before they investigate the problem!
