15-Sep-2016: user network: the issue reported on 14-Sep-2016 has been resolved. However, most TRs (SCUs, PEXARIA, ...) are now blocked due to overflow of events scheduled for execution in about 300 years. In such a case, please power cycle your SCU. Rebooting is not enough. Please make sure your TR (SCU...) is flashed with the "old" Asterisk compatible gateware from January 2016. We are sorry for the inconvenience.
14-Sep-2016: user and timing (TTF) networks: presently no link to the Data Masters. We are working on this issue. Remark: The production network at CRYRING is working fine.

14-Dec-2015: @15:04: data master down - short interruption at CRYRING - @16:00: problem solved
08-Dec-2015: Maintenance week: All White Rabbit Switches of the production system have been flashed to "version: v4.2 (Grzegorz Daniluk); compiled at Aug 28 2015 15:05:21"
07-Dec-2015: After disabling active checks for monitoring, the production system behaved stable for about two weeks. There are occasional "late actions" but we believe this is due to too tight settings of the network latency at the data master.
20-Nov-2015: The production system now monitors all TRs via "passive checks" in Nagios. Within the WR network, we took care of eliminating all traffic except timing message from the Data Master and WR PTP. The system did run for three days without failures. Hm...
17-Nov-2015: Frequently, the production system shows an issue with "late actions". In case this happens, we immediately have to interrupt operation and restart the system. Typically, this should take half an hour. Sorry for the inconvenience.
09 to 13-Nov-2015: production system not available
06-Nov-2015: @1035 production system "up" with crossed fingers as their remain a few issues.
06-Nov-2015: @0900 production system going down for short maintenance
23-Oct-2015: Due to a broken switch and other issues, there was some trouble in bringing the system up again after the power-cut. Now we are back in business.
15-Oct-2015: @1500 production system has been shut down due to an upcoming power-cut. Restart not before 19 October. No timing @ CRYRING. "Programmentwicklungsraum" and "Test Facility" might be affected.
24-Sep-2015: @1821 production system up again. Sorry!
24-Sep-2015: @1806 production system going down for urgent unscheduled maintenance...
