Disruption in CI and related services (internal router not reachable)

(17-05-03) Right now one of our internal routers has connectivity/routing issues. This causes problems with non-public-facing services not being reachable, and this includes various tinderboxes for CI use and intranet traffic used by jenkins. (So bottom line is that right now now gerrit builds are processed) We try to solve this issue with our hosting provider.
