+++ This bug was initially created as a clone of Bug #1905194 +++
All API servers (openshift-apiserver, oauth-server, oauth-apiserver) rely on the TCP stack to detect broken network connections to KAS.
This can take up to 15 minutes. During that time our platform might be unavailable.
There are already reported cases in which aggregated APIs (i.e. `openshift-apiserver`) were unable to establish a new connection to the Kube API for 15 minutes:
- after "ungraceful termination" https://bugzilla.redhat.com/show_bug.cgi?id=1881878
- after a network error https://bugzilla.redhat.com/show_bug.cgi?id=1879232#c39)
Detecting a broken connection should be quicker ideally it should take seconds not minutes.
Pravin, when PRs/bug statuses are ready, help verify (or pre-merge verify) openshift-apiserver, oauth-openshift, and oauth-apiserver, see my steps in the 4.7 clone bug 1905194#c14 ~ c16 (you can ignore other preceding exploring comments there).
