Dear Sir/Madam,

As part of our commitment to continually improve the level of service you receive from LeaseWeb we are undertaking this maintenance.

We are going to upgrade our high volume routers at EvoSwitch dataceter with the new version of Juniper software which is supposed to fix a bug which affected us several times in the past.

The maintenance will take place between 05:30 and 07:00 CEST (UTC+2) on the 13th of June 2013.

Please note there is a similar maintenance announced for 11th June. If the IP addresses of your servers match the following list, you may experience downtime on either 11th or 13th of June.

This are prefixes configured in that part of the network:

[ UPDATE ]
We will combine this maintenance with the chassis swap thus we expanded the maintenance window to 90 minutes, however the actual downtime of your services shouldn't be more than 45 minutes.
