Dear Valued Customer,
City Network would like to inform you that we have planned maintenance as scheduled above.
We are upgrading KNA1 from Newton to Ocata (versions of OpenStack). This upgrade is also path to full GDPR compliance by May of 2018. During the spring we will continue to make upgrades reaching minimum of Ocata but in some locations Pike.
We expect the following in KNA1 Data center:
- APIs: Will be affected sporadically during the service window. Expected down time 2-3 hours.
- APIs in Sto2, Fra1, Lon1, Buf1 and La1: Will be affected sporadically during the service window. Expected down time 1-2 hours.
- Servers: Not expected to be affected, but in certain circumstances we might need to power off or reboot VMs.
- Network: Expect to encounter disturbances for short periods of time. This may occur several times throughout the maintenance window. If all your servers are connected through one router or one network, those servers could lose connectivity during those moments. Overall this part of the upgrade will happen evening and night time.
- Control panel: Expected to be down at moments spread throughout the maintenance window. Down time for the Control panel does not affect servers and network.
