@ -836,3 +836,24 @@ There where power outages in the facility.
**impact**:
* service interruption in the mentioned timeframes till power was restored and equipment back online
017 2022.09.13 | wifi instabilites reported by the facility management
----------------------------------------------------------------------
the facility management reached out and reported that
* they are having issues with the wifi on there new notebooks
* sometimes the wifi is marked as having `no internet` by windows
* they need to switch to the public wifi instead of using the backoffice wifi
* according to the security the wifi is unuseable at around 12:00
**thougts**:
To help diagnose the problem I expanded the monitoring with end to end monitors.
They are pinging two sites in the internet.
One is using the normal wan (like the backoffice) and one is using the vpn (like the public wifi).
See commit `f011562` for details.
I am noticing that sometimes the icmp probes fail, which is odd.
But at the same time the node exporter on `eae-adp-jump01` is reachable.
I will implement another icmp probe that directly uses the `gigacube` without traversing `gw-core01` before.
