Downtime to come?

The host says it’s going to be messing with the network again tomorrow night:

On Thursday January 16th, in a 4 hour window starting at 10pm, we will be moving on to the next step of the Network Improvement Series maintenances. This step is going to involve migrating the network layer from the old hardware to the new designed setup. This is expected to be a near impact-free maintenance; all services will continue to work throughout the migration. As with all maintenances, we will proceed slowly to ensure that, should any problems occur, we will be able to address them quickly.

I mean, this doesn’t guarantee failure or anything, but I’ve seen enough network improvements to know what’s coming.
