All lines on 100% 20CN-REGION-READING and 100% 21CN-REGION-SL dropped at 2011-03-30 17:35:17
We have advised BT
This is likely to have affected multiple internet providers using BT

Update
30 Mar 2011 17:59:58

Two of our ethernet services are down as well, we can only assume routed via the same place. Investigating.

Update
30 Mar 2011 18:13:18

It is very rare for ethernet and broadband services to be affected by a common fault and suggests something major in the openreach back-haul network which serves both services.

Update
30 Mar 2011 18:26:25

Latest is "looks like a major fibre cut near Slough"

No more news yet

Update

engineers on site and that the next update will be at 21:30, apparently

Update
30 Mar 2011 21:59:45

Fault still ongoing, and no confirmed reason for outage yet. Engineers are still on site and trying to find out exactly what the problem is.

Update
30 Mar 2011 23:32:56

The outage has been identifed by BT as an issue with a 21CN core router in Slough. Engineers are trying to restore connections. Earlier information appears to be incorrect - it is not a cable failure.

Update
31 Mar 2011 02:36:18

Further outages for a number of lines on Guildfor BRASs at 01:04

Update
31 Mar 2011 02:58:48

Latest is "There are technical and manageent bridge calls going on", "engneers are on-site at Slugh exchange", and "they had called out CISCO"...

Update
31 Mar 2011 03:00:51

Some broadband lines are coming back on now.

Update
31 Mar 2011 03:03:30

And off they go again... Well, something is clearly happening...

Update
31 Mar 2011 03:09:18

Not wishing to get your hopes up, but some lines tricking back on again...

Update
31 Mar 2011 03:09:49

And off they go... Arrrrg

Update
31 Mar 2011 03:21:27

Many lines back , and seem to be more stable now.

Update
31 Mar 2011 03:29:56

Broadband looks pretty good now. Still two Ethernet circuits down.

Update
31 Mar 2011 03:31:40

Looking in more detail, still quite a few of the BRASes are not back yet, but those that are seem stable.

Update
31 Mar 2011 03:46:06

More lines coming back gradually.

Update
31 Mar 2011 06:30:40

Ethernet back briefly at 6am and off again (this is the 2 affected lines, all others have been fine).

Update
31 Mar 2011 06:32:57

Whle broadband lines have ben gradually coming on, some are still down. It could be that these are lines that need a router reboot, but we have not had confirmation from BT yet as to whether they think the fault is cleared or not. We suspect not quite.

Update
31 Mar 2011 06:35:16

Some broadband lines ent off and back on at 6am, and just now (06:33). BT have in fact now advised that they think the broadband side was fixed at 03:50.

Update
31 Mar 2011 06:36:00

Affected Ethernet lines back on now (06:35)

Update
31 Mar 2011 06:37:56

At this stage, we suggest that if you broadband is still down, try power cycling the router first, and if no luck contact support at 9am.

Update
31 Mar 2011 18:26:32

Closing the issue now as no longer service affecting since this morning. We'll post more details of what actually happened when we get them.
