Switch maintenance on 2012-10-07 - update 1

On Sunday, 2012-10-07 between 22:00 and 24:00 CET we will replace a switch which has accumulated defect ports in the last months. We do not expect any services to have any visible interruption due to the change.

The exchange will be performed by adding the new switch and slowly migrating all connections from the old switch to the new one causing only small, intermittent interruptions (time needed to move the cable plus a few seconds for RSTP to enable the port).

Individual affected services will probably show a temporary increase in response times but no actual failures.

Update 2012-10-08

Unfortunately we had a cascade of technical difficulties that stopped us again from exchanging the faulty switch. We are currently reviewing the needed steps to perform at the data center and are planning another attempt in the next days, probably tomorrow evening (Tuesday, 2012-10-09).

We intend to stick to a tight schedule currently as we want to avoid any further issues of this switch to cause actual issues in the operations.

We will write another announcement once the details are fixed.
