- switches: bgp router-ip, NTP server, syslog server, DNS server
- mail: $mynetworks on goeje
- LVS: pybal config on avicenna for upload.pmtpa
- all external hosts: /etc/sysconfig/network-scripts/ifcfg-eth*
- external squids (srv6-srv10, will): virtual IPs
- load balanced image squids need the new IP as alias on dev lo (/etc/rc.local)
- MySQL: user permissions for our external IP hosts (zwinger, goeje, bart for secure.wm.o etc)
- foreign squids: recreate the config file to update IPs from DNS
