Summary: Wednesday 16/11 @ 10:00am we’ll be migrating the database backend for our broadband control systems to new infrastructure.
What: We’re running a GaleraDB cluster on MariaDB 10.1 and we want to migrate this MariaDB 10.6. Rather than doing this in-situ and having no roll back plan we made new VMs and a new GaleraDB cluster to move to. We’ll shut down access first. Dump the database, copy it over and restore it. Then using salt we’ll push a config change on our systems to point to the new cluster.
A follow up maintenance window may occur where we upgrade the Django framework on our Broadband portal, the impact of this will be decided upon later.
Services affected:
1) Helpdesk and sales teams in our resellers access to https://bbportal.blacknight.com will be limited during this 30 minute maintenance window. We aim to keep the disruption to a couple of minutes but it may take a little longer.
2) broadband authentication for new customers or customers who reboot their CPE – for 10-15 minutes any broadband sessions that drop during this maintenance window will not be able re-connect until this work is completed.
3) Customers with broadband on WHMCS (https://cp.blacknighthosting.com) will not be able to access their Service details during this window.
