Upstream router issue

Our upstream provider in Frankfurt, INAP, started experiencing a problem with one of its routers at approximately 15:30 CEST, causing an apparent loss of connectivity for a few minutes and then continuing packet loss. INAP tells us that they are currently working on rerouting traffic over other devices at this location and expect the situation to normalize very shortly.
