Switch from an LLU Broadband Provider – Leave TalkTalk, Tiscali & Be

Wednesday, April 13th, 2011

Ofcom, the telecommunications industry watchdog, introduced new legislation last year to make it easier for broadband customers to switch provider and take advantage of new, better deals. However, for the million plus LLU customers, this legislation hasn’t changed much.

What is LLU?

In Local Loop Unbundling (LLU), a provider installs their own equipment in the BT exchange, allowing them to provide broadband direct to the end user. This hardware means that customers can expect faster internet speeds, and Ofcom believes that LLU will bring more competition and innovation to the broadband market.

Why isn’t everyone using LLU?

For one thing, LLU isn’t available to everyone. As more exchanges are unbundled, more people can switch to LLU – some through their current provider, others by switching to an LLU ISP.

Unfortunately, LLU providers have also faced a number of service problems; because it uses a different underlying technology to the more common ADSL connection, switching from ADSL to LLU is not always a seamless procedure – some people have been left without any connection at all for weeks on end. Being a relatively new technology has also meant that a few unforeseen problems have cropped up. Migrating away to other providers has also proved to be difficult for customers.

What is the switching process?

People don’t want to get stuck with a provider that they can’t leave; even if they’re happy with the service they still want the option of being able to switch.

Most people now know what a MAC code is. Migration Access Codes allow customers to switch to a new provider without a break in their connection. The use of MAC codes also means that switching has become cheaper as new ISPs just switch the connection over to their service in the local exchange.

LLU MAC codes do exist and increasing numbers of ISPs are now accepting them. They are in a different format to the traditional codes so not all providers will use them. However, having a LLU MAC doesn’t mean you won’t suffer downtime when switching provider.

If you’re switching from LLU back to ADSL, then your new connection will use a completely different technology so you will have to be manually returned to the BT network before your new connection can be set up, and there could be a charge for this.

Even if you want to switch from one LLU provider to another, you’ll still be restricted to those companies currently supplying broadband from your local exchange.

You also need to be aware that if your entire connection is switched over – that includes your line rental – then your phone line will have to be reactivated by BT if you want to return to an ADSL provider.

What if my chosen ISP doesn’t accept LLU MAC codes?

The best way to find out if they’ll accept your LLU MAC is to ask them before-hand by giving them a call.

If they don’t, and you definitely want to go with that provider, then your only option will be to cancel and disconnect your LLU line, and then have a new connection set up by your new ISP, and you will probably have to pay a connection fee for this.

BT Network Tunnel damage leaves UK broadband users without internet.

Tuesday, April 7th, 2009

bt-logoBackground
Reliable information seems difficult to get hold of but from what we know it would appear that there was a major incident causing damage to a BT network tunnel 32 metres below ground in the east of London.  At around 2:30 on Saturday afternoon, what BT will only describe as ‘a third party contractor’ working on the Olympic village bored through the network tunnel severing fibre optic and copper cables. [Note that more recent reports have identified BT Openreach as the 'third party contractor'.]

Impact
The damaged main data artery immediately affected vital services such as mobile phone cell sites, remote connections to traffic light signals and emergency services.  Needless to say, phone and broadband services were also affected.

I am an independant computer services technician working in Lincoln and the surrounding area.  I have had dozens of clients call me complaining of their lack of broadband connectivity (their phone services have been unaffected.) Confirmed affected areas that I have had first hand information about include Saxilby, Fiskerton, Sturton-by-Stow, Ingham, Glebe Park, Nettleham and Lincoln city centre.

Some of these clients lost their broadband on Saturday afternoon.  This would appear to be a direct result of the incident as you would expect.  More interestingly, other users had an uninterrupted service over the weekend but have experienced outages during Monday and today (Tuesday.)  This wouild imply that users accross the country are experiencing ‘planned outages’ in order to cope with capacity issues.  The problem is that no one is being advised of these planned outages.  Some BT reports have even denied that anyone outside of east London is affected.

Comment
Clearly such a huge incident is not going to be repaired overnight.  Imagine a colapsed service tunnel 32m below ground.  Construction workers will have to gain access, make safe and repair the area before any access can be granted to telecom engineers.  Once the engineers get on site the repair job is still mamouth.  In the mean time it would appear that the data can be re-routed.  But at what expense?  The capcity appears to be being borrowed from domestic users from what I can see.

If you have been affected by this issue then please leave a message detailing the extent of your outage and the ISP that you use.  Most of my clients use Tiscali Broadband but what about you?  What are you doing about it?  Will you expect to receive compensation from your ISP?

Update (Wednesday morning)
I have just been in touch with my contacts at Tiscali to try and get some more info.  The quote from their technical team is as follows:

“We identified a further issue yesterday morning (Tuesday) relating to the BT outage, there is a further two STM-4 (622Mbps) IPStream pipes down which is around 15% of our (Tiscali’s) overall IPStream capacity so this will be causing some customers to be without service across the UK. BT are working on resolving these two breaks but as there is 1186 cables to be repaired it won’t be a quick fix.”

It’s nice to be told ‘something’ but it begs more questions than it answers.

Update (Good Friday)cable_damage
There are a couple of photos on Flickr now.   The big orange thing is the boring machine cutting through the cable tunnel.  Actually it’s a much tidier job than I’d imagined!  Still, it’s had a huge impact on our broadbnad service.  (Note that I have no way of telling whether these photos genuinely releate to this issue.)
