Uptime: The Movie

[readingj@CERF.NET (John D. Reading)]

I realize that there may yet be more who want to get their inputs 
in on the uptime question, but we can't wait forever, you realize. 
But first, some moralizing:

When I first posted the request, I was a little hesitant, because 
I thought you would all think I was weird. I mean, I have avoided 
rebooting a machine that had been up a long time, just because I 
didn't want to break its record. However, from the responses that 
came back, I can see that I am not alone. Sorry about the bandwidth, 
but we can have a little fun along the way, can't we?

Anyway, on with the summary:

Our server, OSSABAW (a 3670), is currently at 6 weeks, 6 days, 7 hours.
I think we've beat that in the past, but I can't verify it.

METHUSELAH               30 weeks 2 hours 40 minutes 50 seconds

Well, that just beats my record of 28 weeks 6 days 20 hours 40 minutes
6 seconds from 19 February to 10 September of this year.  I was shut
down because of an A/C failure in our machine room.

The best I've seen in normal operation was somewhat more than 13 weeks
for a file server here at SCRC.  We only shut it down because we were
moving our whole site to a different town.

Months ... many of them. 3 - 5 at least.

(Note - Methuselah still beats this, apparently JDR)

As a different measure of age of a boot, I look at words consed
(after all, keeping a machine going is no trouble if you're not using 
it).  The highest I've seen here is about 500,000,000 words
(from Show GC Status).

From: p2@porter.asl.dialnet.symbolics.com (Peter Paine)

We have had a MacIvory II(fx) stay up for more than 3 weeks so far.
Power cuts are the usual problem. 

58% of a year beats our L-mach records flat.

How do other systems standup? ... Sun, Vax, HP, RS6000, NeXT, ...

(Our MacIvory has been up a few weeks at a time, but it is no longer
 on the local net. I just checked in at Argonne National Labs, and
 their record right now is 154 days [22 weeks] on a lightly used Sun
 of some variety. On the Alliant fx2800 I usually use the longest has
 been around 45 days, but it was a power outage that did us in [it
 is a very new machine] - JDR)

----------------------------

So, as near as I can tell, Methuselah is the winner at 30 weeks,
although I think it is pretty obvious now that Dave has an obligation
to let us know when Methuselah finally ends his streak, so those of
us with machines currently on a streak can know what we need to
shoot for.

Thanks for your indulgence, and I will try to make my next request
a little more serious :-)
