[arfnet-announce] On today's power grid failure

[arf20 <arf20@xxxxxxxxx>]

Hi,

As you may have noticed, ARFNET was down from around 1200 to 2300 UTC+2 
on April 28th.

This was due to a continental-wide power grid failure (yikes) that 
happened around France, Spain and Portugal apparently, for reasons 
unknown other than an unforseen 15GW drop or something like that.

I could do nothing about this, however, this was a real good test of the 
UPS and mechanisms, and the test passed. The UPS detected several power 
failures starting at 1100, the final one being at 1233 (the official 
outage time). The UPS kept things running until the shutdown reached the 
timeout target of 15 minutes and begun shutting down VMs at 1248, 
sending the last SIGKILLs at 1251 and powering down.

So yay. Everything is back up now, nothing is lost. Should anything go 
wrong though we're cooked because I'm not usually on site but at 60km 
away without transport so yeah.

Good night cuties :3
