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
Two of our ethernet services are down as well, we can only assume routed via the same place. Investigating.
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.
Latest is "looks like a major fibre cut near Slough"
No more news yet
engineers on site and that the next update will be at 21:30, apparently
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.
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.
Further outages for a number of lines on Guildfor BRASs at 01:04
Latest is "There are technical and manageent bridge calls going on", "engneers are on-site at Slugh exchange", and "they had called out CISCO"...
Some broadband lines are coming back on now.
And off they go again... Well, something is clearly happening...
Not wishing to get your hopes up, but some lines tricking back on again...
And off they go... Arrrrg
Many lines back , and seem to be more stable now.
Broadband looks pretty good now. Still two Ethernet circuits down.
Looking in more detail, still quite a few of the BRASes are not back yet, but those that are seem stable.
More lines coming back gradually.
Ethernet back briefly at 6am and off again (this is the 2 affected lines, all others have been fine).
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.
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.
Affected Ethernet lines back on now (06:35)
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.
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.
