Affects: Traffic of related vlans in DBA

As part of the infrastructure change that is currently going on in DBA, Now physical connections of Zone4 and Zone5 is completed, we will be moving the remaining VLANS to the new infrastructure.

We have planned in the following maintenance:

Tuesday 23 October, VLAN 200 tm 300 (Completed)
Thursday 25 October, VLAN 301 tm 377 (Completed)
Wednesday 31 October, VLAN 378 tm 454

During this time, network connections per VLAN may be interrupted up to 1 minute.

Update 2018-10-23, 07:04: The first set of vlans (200 to 300) are moved, we have monitored the stability and now marked the maintenance as completed.

Update 2018-10-25, 06:46: The second set of vlans (301 to 377) are moved, we have monitored the stability and now marked the maintenance as completed. We did have noticed on a few vlans there have been longer than expected downtime. This is resolved automatically. The information we have gathered will be used for replication to ensure lowest downtime possible on the next set.

Update 2018-10-31, 10:39: The last set is moved and everything was stable without any issues.
