NTP4.usv.ro - OPERATING STATUS / DEVELOPMENT INFO / ACCESS RESTRICTIONS

(03/06/2011) - Importance:

We changed the servers location in a new building and positioned the GPS receivers on the rooftop, with almost 100% visibility to the sky. This means
improved performance compared to the old instalation. The hardware configuration didn't changed.

For the next 4 months, Internet connection failures may occur, so service interruptions are inevitable. Even our Internet connection will be down,
the time servers will work in the background without degraded performances, as we use no Internet information to keep the time accurate.

The servers location will change starting the 1st of June 2011. Beginning the 23rd of May 2011, we planned a series of test in order to find the best
configuration for the servers for the period with limited or no GPS visibility to the sky. The PPS Rubidium source will be available as a sync source.
For the next 4 months, Internet connection failures may occur, so service interruptions become inevitable.

We changed the main ISP link from AS6830 to AS2614 (via AS20965) having now a very good international connection (with several external active
routes and peering). The maximum download / upload speed is now up to 30 Mbps, more than the previous limit. By the end of this year we have as
a target to upgrade the national connection between Suceava and the Roedu.net backbone to 1 Gbps. The total upload / download limit for the
external link (GEANT2 connected) of the central network backbone in Bucharest is 2 x 622 Mbps.

Post event information: The server was unavailable for various time intervals, due to route propagation process, between 06:25UTC to 19:00UTC.

We replaced the 14.318182 MHz crystal on the motherboard with an ICS525 Programmable clock synthesizer controlled by the 10MHz
Rubidium PRS-10 frequency standards output.
