CKDB Restart at 16-Jul 6:30am UTC No mining will be affected. Web/API outage is expected to be less than 10mins while CKDB restarts. The restart time is approximate, it will occur when the shift ends around that time.
CKDB Restart

CKDB Restart at 30-May 8:45am UTC No mining will be affected. Web/API outage is expected to be less than 10mins while CKDB restarts. The restart time is approximate, it will occur when the shift ends around that time.
US Passthru Server upgrade
Status: Complete
US Passthru Server upgrade at 10-May 8:00am UTC The US Passthru Server, that ~60% of miners use, will be upgraded. This will be a 5 minute outage for all miners pointed to all stratum.kano.is server addresses. None of the nodes (NL, DE, SG, JP, NYA) will be affected by the upgrade.
If you have a node as your 1st backup, then you will simply failover to the node during the upgrade, then failback after the upgrade has completed.
Since forcing 2 failovers takes 10 minutes in cgminer, and the upgrade takes less than 5 minutes, all miners will just failover+failback for the upgrade. All US Passthru Server miners will failover to their first backup, then failback after the upgrade completes.
NL Network Maintenance
Status: Complete
NL Network Maintenance at 3-May 3:00am UTC until 3-May 4:00am UTC The data centre for the NL node will be performing network maintenance. The provider has stated there may be a very short outage during the maintenance.
Any short outage would lead to a short failover to your backup mining settings in your miner. Ensure you have a backup node configured in your miners in case of an outage, or unexpected problems.
For miners mining to nl.kano.is a good choice for first backup would be de.kano.is or nya.kano.is Ping them both to see which is closest to you.
CKDB Restart
Status: Complete
CKDB Restart at 17-Apr 11:30am UTC No mining will be affected. Web/API outage is expected to be less than 10mins while CKDB restarts. The restart time is approximate, it will occur when the shift ends around that time.
NYA node Server upgrade
Status: Complete
NYA node Server upgrade at 16-Apr 11:00am UTC Only the NYA node will be affected, no other mining will be affected. There is no actual expected mining outage, however there will be two reconnects during the upgrade which may result in a failover+failback for some miners.
The upgrade process will be to shift NYA miners to a temporary passthru via DNS with a disconnect/reconnect, then to upgrade the NYA Server, which will take less than 5 minutes, then after 30mins, to shift all NYA miners back.
The total time is expected to be 1 hr 5 minutes - waiting 30 minutes for the DNS change and restore. Again, there is no expected outages for mining, only an immediate disconnect/reconnect after the DNS change and restore, which may result in a failover+failback for some miners.
NL & DE node Server upgrades
Status: Complete
NL & DE node Server upgrades at 10-Apr 9:00am UTC Only the NL & DE nodes will be affected, no other mining will be affected. There is no actual expected mining outage, however there will be a couple of reconnects on each node during the upgrades which may result in a failover+failback for some miners.
The upgrade process will be to shift DE miners from DE to NL via DNS with a disconnect/reconnect, then to upgrade the DE Server, which will take less than 5 minutes, then after 30mins, to shift both NL & DE miners from NL to DE via DNS with a disconnect/reconnect, then to upgrade the NL Server, which will take less than five minutes, then after 30mins, to finally shift all NL & DE miners back to their original nodes with the original DNS restored.
The total time is expected to be 1 hr 40 minutes - waiting 30 minutes for each DNS change to take effect. Again, there is no expected outages for mining, only an immediate disconnect/reconnect after each DNS change, which may result in a failover+failback for some miners.
JP Japan node Server upgrade
Status: Complete
JP Japan node Server upgrade at 1-Apr 11:30pm UTC Only the JP Japan node will be affected, no other mining will be affected. Mining outage expected to be less than 5 minutes. Add another Kano node as Pool2 if you only use one Kano node.
SG Singapore node Server upgrade
Status: Complete
SG Singapore node Server upgrade at 1-Apr 11:00pm UTC Only the SG Singapore node will be affected, no other mining will be affected. Mining outage expected to be less than 5 minutes. Add another Kano node as Pool2 if you only use one Kano node.
Web Server upgrade
Status: Complete
Web Server upgrade at 31-Mar 3:00am UTC No mining will be affected. Web outage will be less than 5mins
