Emergency ADSL Connections

Posted: Friday, March 30th, 2007 at 15:09 by Neil Watson

Due to the problems being seen with SMTP traffic, we need to terminate some ADSL customers onto different equipment. As such we are forced to disconnect these users. We will be performing this in the next 15 minutes and apologise for any inconvenience this may cause. Customers should automatically reconnect, however if this does not happen please reboot your router / modem before contacting support.

SMTP mail problems

Posted: Friday, March 30th, 2007 at 13:06 by Neil Watson

Some users are reporting problems sending mail through and Our investigations indicate that the only users who will be experiencing problems will be those that are using Outlook Express. This has been tested in our labs and identical messages sent through an alternate client (Thunderbird) have sent without problem. The number of connections being made to our servers as a result of this issue has obviously increased the demand for resources, we have therefore added an additional server to the SMTP pool to assist. We will continue to monitor the situation.

Outgoing mail problems

Posted: Thursday, March 29th, 2007 at 11:09 by David Derrick

The mail servers which provide outgoing mail service for some customers are running very slowly at the moment. Engineers are investigating.

  1. David Derrick says:

    It appears that some mailing lists with lots of undeliverable addresses had clogged up the servers. This combined with a higher than average amount of other mail to cause the slowdown. The servers are running normally again and we are continuing to monitor them.

Radius problems

there is a problem with our radius servers at the moment, looks like some users have been deleted from the database so those users will not be able to connect right now.

we have a programmer and engineers looking at the problem

  1. Steve Lalonde says:

    51 users were missing from the radius database they have now been restored.

LNS crash

Posted: Sunday, March 25th, 2007 at 10:15 by Steve Lalonde

The new 10k LNS crashed twice last night and while I was looking at it this morning to work out why it just stopped responding.

I have removed it from the pool, all sessions are now being handled by the original hardware.

I have also had to disconnect some users from the global-switch 1 central to rebalance the load caused by the crashes.

  1. Steve Lalonde says:

    Looks like the crash was caused by a known bug, I have upgraded the software to the latest fixed version and I’m putting the box back in the LNS pool.

DSL Maintenance Incident report

Final 155 segment of central 3

Posted: Saturday, March 17th, 2007 at 10:10 by Steve Lalonde

The final segment of central 3 will be enabled on Monday 19th March. We are enabling this last segment a week ahead of schedule due to the BT maintenance work on central 1 on Tuesday night (details here).

  1. Steve Lalonde says:

    the new segment is now live.

    Note: GS1 central is currently very full both telehouse centrals have available capacity.

Central 4 install delayed

Posted: Saturday, March 17th, 2007 at 10:00 by Steve Lalonde

BT have delayed the install of central 4 again, last date given was 28th March but that is looking unlikely. It seems that no one in BT knows how to raise a method statement to allow them to install the fiber in to their own rack in the Global Switch meetme room.
