This morning I did some quick maintenance to all the nodes. Operating system updates and patches have been applied but also the hardware has been upgraded. When I started the pool I chose to run the nodes with 2 CPU’s and 4gb of RAM. This was still sufficient to run but to preserve stability in the future the hardware has been upgraded to 4 CPU’s and 8gb of RAM. In order for this upgrade to be performed there was a downtime of 10 minutes.
