Upcoming network maintenances - New core infrastructure

As part of our commitment to continually improve the level of service WorldStream provides, we want to inform you about upcoming network maintenances.

About 2 weeks ago a first outage occurred on our network infrastructure. Our network staff discovered we were facing hardware limitations on our Cisco platform which we only implemented last December 2015. During the last two weeks we have made some major fixes to reduce the impact of these hardware limitations.

As we were facing these problems on our core infrastructure we have decided to replace the complete core router ánd core switching platforms with the latest Arista equipment. Step by step we will phase out the current cisco platform by new Arista equipment. The new Arista equipment can scale up to 30Tbit/s of utilization, with deep buffer architecture to handle microbursts easily.

During the next 6 weeks we will perform the following steps in order to maintain and improve the quality of our services:

Replace current Cisco core router infrastructure by new Arista Equipment - 30/09/2016 between 2 and 7AM CEST.Replace current Cisco core switch infrastructure by new Arista Equipment. - To be announced.Expand our Telia Sonera port capacity with another 100Gbit/s. Within 30 days.Expand our AMS-IX port capacity with another 100Gbit/s. Within 30 days.

The first maintenance will take place at the 30th of September, between 2 and 7AM CEST. During this maintenance we will replace our core routers. We will perform this implementation and replacement gradually, and will do our utmost best to bring the impact to a minimum. However, during this maintenance bursts of higher latency and suboptimal routing paths will occur.

If you would have any further questions related to the issues please feel free to contact us at or on our live sales chat located
