We will be performing a rolling update of network configuration across our entire fleet in Denmark today and tomorrow. This update is to ensure the stability of our network and solve a long-standing issue whereby some customers have experienced sudden loss of connectivity due to routes beind dropped on our hosts. This update will eliminate this long-standing issue.
Unfortunately, a subset of our customer instances need to be touched whereby our team adjust the network configuration inside your instance. This will typically only impact customers who have created servers with us recently - older instances and instances created within the last couple of weeks are unaffected and will not be touched.
The operations usually just mean a reload of network configuration whereby - at worst - you will see a few packets lost and that's it. Only in rare cases where network configuration was already non-standard or bad beforehand in a customer instance will scenarios come up where you may see some disruption. We expect this to be minimal.
Since this is a large task, we expect this maintenance to last throughout the day today and all day tomorrow, possibly longer depending on progress, in which case we will update here.
Thank you for your patience and understanding.
