Storing sites en e-mail bij Mijn Domein (opgelost)

Hosting provider Mijn Domein kampt momenteel met een storing op haar netwerk, waardoor mail en websites niet bereikbaar zijn. Sites zijn vanaf sommige providers wel bereikbaar en andere verbindingen weer niet.

Update 10:32
Sites zijn vanaf UPC en KPN verbindingen grotendeels wel bereikbaar. Lijkt op peering issues tussen Mijn Domein en verschillende backbones. Vanaf Ziggo is Mijn Domein compleet niet bereikbaar volgens meerdere bevestigingen.

Update 10:48
Mijn Domein bevestigt routing issue. Grote up-link provider ervaart problemen.

Update 11:00
De verbindingen lijken hersteld. Mail en sites moeten weer bereikbaar zijn. De storing werd veroorzaakt door een storing bij de netwerkleverancier Proserve, welke op haar beurt de storing had te danken aan één van haar netwerkproviders. Er is spoedonderhoud gepleegd aan hun Cisco 7609 routers in het EUnetworks datacentrum in Amsterdam, welke is afgerond. Er wordt nog spoedonderhoud gepleegd aan apparatuur op de andere locatie Dataplace.

Core router software update (CRS-EVO)

Startdate: September 1st 2010 06:00:00(CEST)
Enddate: September 1st 2010 07:00:00(CEST)

Dear Customer,

The outage our network experienced Friday 27-08-2010 (http://noc.leaseweb.com/status.php?i=557) was caused by a bug in the IOS-XR software which runs on our Cisco CRS-1 core routers.

More information about the bug can be read on Cisco’s page concerning this issue.

During this maintenance window we will install the update on our CRS-1 router located in EvoSwitch.
The router will be rebooted.
Before the maintenance starts we will reroute all traffic to the core router located in Telecity-2.
Customer traffic loss is not expected.

Kind regards,

AMS-IX connection maintenance

Startdate: April 22nd 2010 07:00:00(CEST)
Enddate: April 22nd 2010 08:00:00(CEST)

Dear Customer,

During this maintenance we will migrate to a bigger chassis the second side of the DWDM system which we use to connect our Cisco CRS-1 router at Evoswitch to AMS-IX.
This is one of two connections we have to AMS-IX, so no impact is expected as our whole AMS-IX traffic will be rerouted to our second Cisco CRS-1 router at Telecity 2. The expected downtime for our AMS-IX connection at Evoswitch is about 20 minutes within the maintenance window.
This is the last of three needed maintenances. After this one we will be able to finally increase our AMS-IX capacity from 120 Gbps to 140 Gbps.

Kind regards,

AMS-IX connection maintenance

Startdate: April 20th 2010 07:00:00(CEST)
Enddate: April 20th 2010 08:00:00(CEST)

Dear Customer,

Due to our increasing traffic we have recently ordered two additional connections from our Cisco CRS-1 router at Evoswitch to the AMS-IX at the Nikhef datacenter in Amsterdam. Unfortunately AMS-IX switch we are connected to has no more free ports and all our AMS-IX ports at Nikhef have to be migrated to a new bigger switch.
The maintenance will affect one of two connections we have to AMS-IX, so no impact is expected as our whole AMS-IX traffic will be rerouted to our Cisco CRS-1 router at Telecity 2. The expected downtime for our AMS-IX connection at Evoswitch is about 20 minutes within the maintenance window.

The timezone is CEST (UTC+2).

Kind regards,

[update 22:38]
The router experienced several problems, and issued a redundancy failover to the backup route processor. The failover caused all BGP sessions to flap. Traffic flow has been restored on the router ahter the failover.
