This page describes processes and requirements regarding Blockchain Node Engine
upgrades and maintenance windows.
Node maintenance
Blockchain node maintenance occurs when the Blockchain Node Engine instance is
updated. This includes:
Upgrades of blockchain client software itself (e.g. an Ethereum upgrade)
Updates to Blockchain Node Engine business logic. For example:
New features
Bug fixes
Routine maintenance
GKE cluster software updates
Maintenance updates on the underlying infrastructure
Node downtime
Although it is not common, node upgrades can cause downtime from as little as
a minute or less to up to 40 minutes. In some cases, the node pod itself does
not need to be restarted and there is no downtime.
Maintenance windows
We plan to provide updates during regular windows as follows; however, there
could also be unplanned urgent updates. We will provide as much notice as
possible.
