from the folks who host Kukla's Korner.

During our standing maintenance window tonight we will be making some needed adjustment to our core routing infrastructure. We generally strive for a longer notification period before work like this, but the working being done was deemed needed sooner rather than later.

Maintenance Window: 11pm to 2am (Central US)

Outage length: 15 to 45 seconds x 3 or 4 separate incidence during the window.
