Dear customer,



During this maintenance window we will upgrade the software on our high volume routers at Evoswitch in Haarlem. The maintenance will take place between 6:00 and 7:00 CET (UTC+1) on the 17th of November 2011. You may see up to 15-20 minutes downtime.



Within the same maintenance window we will also upgrade the software of our peering router in Frankfurt, Germany. There should be no serious impact, however it is possible you may notice temporarily higher latency or small packet loss when traffic is shifted towards alternate paths.



Affected IP ranges for high volume routers upgrade:

46.243.0.0/22

62.212.82.0/24

62.212.85.0/24
