 ### Outage log
 
 * 21st of June 2021 20:15-22:29 UTC: What was planned as a 5min outage to set up a 2.5Gb Ethernet card, escalated when it turned out my soon-to-be-discarded Raspbian installation had *the entire network settings menu* disappear permanently, leading to huge problems assigning a static LAN IP to it.
+* Intermittently from 24th to 26th of June 2021: In relation to upgrading to an ARM64 distro, there were problems with *firewalld* and a seemingly dead Ethernet overvoltage protector (APC PNET1GB) that led to frequent downtimes of a few minutes every few hours.
