[AusNOG] DC undervoltage issues

[Damian Guppy]

  IANAL but I would imagine in absense of them specifying they would be
bound to deliver power to ANZ standards of 230v +10% -6% (iirc) ie 251v-223v

I assume you are running a line interactive UPS?

Subject: [AusNOG] DC undervoltage issues

Evening noggers, hope you're all surviving the heat, especially in VIC!

Speaking of, in 2 DCs were seeing borderline undervoltage on our UPSs (yes
we run them even with A+B power because sensitive equipment), I've read
that there are power issues in VIC at the moment, but I thought they were
limited to residential zones (with rolling black/brownouts)?

Anyone else seeing this, or have comments?

As a side question, does anyone (perhaps Bevan?) know if DCs will manually
switch to genny/backup power in this sort of scenario, if so details would
be nice.

(with regards to that, I looked at one DC contract and it doesn't mention
anything about the specifics of power delivered, just that it is A+B with X
battery backup and Y generator capacity, and Z SLA, doesn't mention what
sorts of voltages would break said SLA...)

Anyhoo, cheers!

PS, also seeing strange intermittent issues with Telstra and Pacnet
connecting to local google and others, not sure why the power quality would
affect that, but..
