BIT NL Cloud vlan migration

BIT NL Cloud vlan migration

Urgency: Planned
Affected services:
– Virtual machines
– Virtual datacenters
Expected impact:
– Short interruption of network connections
Customer intervention required: No
Reference number: 203260

Summary:

During the maintenance several IP ranges will be migrated to different vlans, which will also involve moving the gateways to other routers within the BIT network. Virtual machines that use an IP address from one of these ranges, or are routed via an IP address in these ranges, will be unreachable for up to 10 minutes during this migration.

Details:

To make the network configuration in the BIT NL Cloud more robust and flexible, we are migrating a number of IP ranges to different VLANs. The gateways for these IP ranges will also be moved to a different set of routers within the BIT network.

During the maintenance work virtual machines or VDCs in the BIT NL Cloud with IP addresses in the range being migrated will be unavailable for approximately 10 minutes. This also applies to IP ranges that are routed via an IP address in one of the ranges below.
