<p>The questions left to be answered for Vocus is why did it take 12
hours to restore one rail. Where was the static bypass and failing
that where was the maintenance bypass. Im guessing that's what
it's on maintenance bypass now and the slow action may have
something to do with the public holiday in Vic.. <br>
</p>
<p><br>
</p>
<p>I shouldn't speculate. But it is fun. <br>
</p>
<p><br>
</p>
<p> Something seriously let go in that UPS. If i had to put my
electrical engineers hat on I would say their load capacitor
maintenance was not done and let go. Or someone was working
upstream and broke the natural/earth bond. But there's a lot of
parts in a system like that , most modern DC UPS setups are fairly
robust. I once had 3 strings of batteries catch fire and melt
down and the UPS didn't miss a beat other then spewing a lot of
alarms. We moved strings around on the fly and nobody even
noticed. <br>
</p>
<p><br>
</p>
<p>The other things that seems odd is why did an A failure trip B.
Sounds like a single supply is at surge/break capacity. Also a
worry. <br>
</p>
<p><br>
</p>
<p>But in the end we all have redundancy around 530 Collins right ?
Right ? <br>

SY1 apparently experienced a full power outage back in July
2009, according to AusNOG Archives. Some reported full outages,
some partial. Was not a DC fault though, looks like a much
larger grid issue where a fault at the Bayswater Power Station
in the Hunter Valley (which affected generators in QLD and VIC)
caused about 1000MW to be dropped from the grid, resulting in
rolling blackouts across QLD, NSW, TAS, SA and VIC.</div>

<p>SY1 had A or B fail a few years back if my memory serves me
correctly. But I was referring London and Manchester which
both had total outages in recent years.

<p>Yea because Eqinix has never had a power outage. :) </p>
<p>I think it's a little premature to judge at the moment.
Doesn't sound good based on the current info but we have
all had bad days im sure.
