More Network Upgrades – Minor Downtime Possible

We’re doing some more work on upgrading our network, or as I prefer to refer to it, spending more of our cash on hardware!
The important information is as follows:
Time / Date: Thursday March 8th-9th – 23:00 – 01:00 (IST)
What: Network upgrades.
Service affecting? – yes
Full details:
Overview: To facilitate the growth of our colocation facilities in DEG we need more ports in our core access layer. Currently there are 2 x 24 port switches currently connecting back to each equipment cabinet. There is a port from each switch into each cabinet and we use spanning tree to fail over in the event of a network failure at that layer.
We are putting in 2 x Cisco 2960G-48TS 48 port GigE switches to replace the current infrastructure and thus giving us more room to grow and increased bandwidth at this layer.
Expected Downtime: We expect the whole change over to take up-to an hour, we’ll do all the preparatory work, racking and configuring the switches before hand. All we’ll have to do is move the cabling to the new switches and do a lot of testing. So please expect connectivity to both the old and new networks to be intermittent during this window.
If you have any issues connecting to your site/server after the maintenance window has completed, please e-mail support@blacknight.ie with details and we’ll deal with your issues immediately.
