Dear LeaseWeb customer,

To ensure we can provide you with the highest quality infrastructure and services, we recently announced the migration of all U.S. racks and servers to a new state-of-the-art facility within our U.S. datacenter in Virginia (please go to <a href="http://leasewebnoc.com/en/maintenance/us-important-maintenance-announcement">HERE</a> for the full announcement). During this relocation, we will perform the following activities:
• Disconnect all racks from power sources and network uplinks
• Move complete racks from their current location to their new location
• Reconnect the racks to new power and network infrastructure
• Bring all servers back online

The relocation will take place between 17 – 20 December 2012, from 11:00 P.M. – 7:00 A.M. EST.
Below you will find the schedule for the relocation, based on IP ranges. We kindly request all customers to turn off their affected servers before the relocation.

<b>Expected downtime</b>
While we will minimize any downtime as much as possible, we expect affected servers to be offline for about 30 – 60 minutes.

<b>After the maintenance</b>
After a server has been relocated, on-site engineers will check if it restarted correctly. An End-of-Maintenance Notification will be sent once a server is back online.

<b>Please contact LeaseWeb support in case of any issues</b>
LeaseWeb will of course perform the relocation with the greatest care. However, should you receive an End-of-Maintenance Notification while your server is not yet online, please notify LeaseWeb Support by replying to the notification. Alternatively, you can email any issues to [email protected].

We apologize for any inconvenience caused and thank you for your understanding.

Dear Sir/Madam,

We are currently having issues with out High Volume Network in Evoswitch. You might experience higher delay, or connectivity issues.
We are investigating and we will update this posting.

[Update@11:25]
We believe traffic has been restored and issue has stopped.
We are still investigating.

[Update@11:45]
We think we have found the cause of the issues.
One of the internet exchanges we connect to has experienced issues with a linecard we are connected to.
It seems our core-router connected to that blade received an extremely large amount of packets per second during short period.This in turn led to high CPU load which caused other BGP sessions to become unstable.

The internet exchange has reported that their equipment seems stable again, and they are working with their vendor's support to investigate.

We will also continue to investigate, and monitor the situation.
For now the Leaseweb network seems  stable, if you do still experience issues, please contact our support dept.

Dear Sir/Madam,

We are experiencing a power issue/hardware crash on our router 1 in Schuberg Philis datacenter.
As it is a redundant setup, router 2 has taken over.
All services with correctly configured redundant uplinks are online.

@Update 11:25
Router is now back online and connectivity should have been restored.
The cause of the issue was a software bug.
We will schedule a maintenance in the near future to upgrade the software to latest version.

Update at 13:11
Currently we are having a network issue. An engineer is working on this. Please stand by for updates.

Update at 13:15
The issue is resolved and was caused by a loop on the network. During the outage we noticed some irregularities which during troubleshooting afterwards caused the loop.

Time: October 29th 2012 19:54:00
Customers with services in our USA datacenter near Washington DC we would like to inform.

In preparation for hurricane Sandy, standard emergency procedures are in place and the team is on standby 24/7 to respond to any support requests. In the event of any issues, updates will continue on this page throughout.
