Hello all,

Due to the recent acquisition of Woaf Tech Ltd we are now in a position to
change the network to benefit ourselves, and for larger scale changes, our
new inherited customers. The problems of this weekend highlight the need to
restructure our connection to our new core.

However, as a result of these changes, we will need to renumber IP Addresses
in use by our equipment and by customer equipment. The following work is
scheduled for

The current plan is to move from the current shared netblock
213.230.205.0/24 to our own netblock at 213.230.209.0/24.

We intend to reorganise the address space a little whilst we are at it and
we will try to keep changes to a minimum - changes will mostly impact shell
customers and dedicated server customers with extra IP Addresses - these
addresses will be shuffled to make better use of the new netblock, and will
mean that you get contiguous address space instead of the rather random
allocation you have at present.

Colocation and Dedicated server customers who only have one IP address
should not be affected other than having to change the third octet from 205
to 209.

A full map of IP address changes will of course be published ahead of time
in the next week or so, and extra DNS and MX facilities will be made
available for all customers who wish to ensure as little disruption occurs
to their services as possible.

Unmanaged dedicated server customers and colocation customers will need to
contact us to arrange root user login details for your machine so that we
can change your IP Addresses for you on the date of changeover, if you are
not able to/happy to do this yourself.

We will be making dynamic dns hostnames available to customers to use to
point their DNS records at a minimum of 48 hours before the network renumber
is scheduled to take place. This will allow your site to be reachable within
about 10-15 minutes of the network addresses being changed, rather than
waiting a full 24 hours for the regular DNS to update. Full details of how
this will work will be published to this list in the next couple of days. We
will, in addition, be keeping ns0.lchost.net and ns2.lchost.net
(213.230.205.115 and 213.230.205.11 respectively) live on those network
addresses for a few months while we ensure all changeover work has been
completed successfully, and customers have migrated their dns to the new
nameservers (which will be published on wednesday).

Once the changeover is complete, we will be increasing the international
bandwidth capacity of our segment of the network which will hopefully quash
the recent loss and lag issues some people have reported at peak times.

We apologise in advance for any inconvenience this move will cause, but
would ask you to bear in mind that it is essential work in order to improve
the network performance for you all.
