Two of our circuits to DE-CIX (German Internet Exchange) and one to Netnod (Swedish Internet Exchange) will be maintained.

No impact is expected as we will reroute our traffic to other links. During traffic switching and tuning there may be small temporary packet loss or latency increase.

Dear Customer,

During this maintenance window we will upgrade the core router at Evoswitch.
We will add interface modules.
After the upgrade we will have 16 extra 10GE ports available.

There is no impact expected.
The router supports O.I.R. (online insertion and removal)

Kind regards,

LeaseWeb NOC

[UPDATE]
I’m sorry to report I made a mistake when entering the maintenance date.
The correct date is the eighth of December 2009.

[UPDATE]
We’ve received notification from our distributor.
Delivery of the new modules has been postponed.
As such we have moved this maintenance window forward as well.

[UPDATE]
Delivery has been pushed forward, therefore the maintenance window has been brought back to Monday 7th of December.

Startdate: November 30th 2009 22:00:00(CEST)

[Update 27.11.2009 12:00]
We have just received emergency update from our carrier: there is a possibility the fiber backbone rerouting may take them longer than previously expected, so in the worst case this maintenance may last even to 9:00 AM CET.
As we have backup capacity on other links we do not expect any serious impact on our network.

[UPDATE 02:58] It seems some feeds had a short power dip. This is not certain yet. We are still investigating.

[UPDATE 03:12] Some colocation customers are causing ethernet loops, these interfaces are being shut now.

[UPDATE 03:17] to clarify, the loops did not start the problems, it seems that the colocation customers switches are causing loops after the power dip.
All looping interfaces have been shutdown.

[UPDATE 03:39] Four extra engineers are at the datacenter. And some more underway. If your server is still not online please contact support via email.

[UPDATE 07:20] A customer in Hall 2 who was replacing network equipment caused a loop which caused partial unreachability in Hall2.
