xrp.ninja Ripple validator crashed last night due to low free disk space
The above graph shows what happened. I did get an alert from GCE that disk usage was high. I have an alert policy which says alert me if disk usage is over 80% for more than 5 minutes. However, it was too late, so I didn't get up and thought maybe it could resolve on its own. But it didn't. And GCE didn't keep alerting me, which surprises me.
