The server went down with the following error today:
Record: 216 Date/Time: 02/20/2020 11:16:09 Source: system Severity: Critical Description: Correctable memory error rate exceeded for DIMM_B1.
I've depooled it until the DIMM module has arrived/been swapped.
The host has been down a week, hence it has been removed from PuppetDB and the Netbox report catched it.
Updated Netbox setting it's state to Failed. Please follow https://wikitech.wikimedia.org/wiki/Server_Lifecycle#Active_-%3E_Failed
after puppet runs host was added back in Icinga.
then: CRITICAL: 944 mismatched wikiversions
after a looong scap pull it is all green now
will pool again
