FYI, for us its only the website and public pro server everything else will remain up.
Dear Piercy

We are currently performing a system migration and will be expecting several downtimes for some of our key services over the next three days. We will be performing the service migrations during the following operational windows:

21/07/10 00:00 – 08:00
And
23/07/10 00:00 – 08:00

We are planning to move all services during the first operational window however if we anticipate complications which may require us to postpone the move until the second operational window.


The following services will be affected:

Order System – We will not be taking any new orders until the migration is complete on Saturday, we can however still upgrade servers or install new servers for you via the cpanel ticket system.

Cpanel, Public Websites and FTP – All YCN hosted websites will go down during our webserver migration, during this time you will not be able to access the cpanel, ycn public website or the forum. These services will not be accessible for approximately 2 hours.

Websites – All Client websites will go offline for approximately 4 hours.

Email Server – When we move our mail server we will not be able to receive emails and will not be able to offer email support

Teamspeak2/3 and Mumble – There will be a downtime for approximately 2 hours.

Bouncers – Bouncers from the bouncer server: 78.129.194.2:31337 will be down for approximately 1 hour.


There will be no interruptions to any game servers during these periods.

We are also carrying out a maintenance on our UK game servers on Friday 23/07/10 between 11:00 and 15:00. There will be a downtime of approximately 1 hour for all UK based game servers and bouncers.
