If there's some service interruptions to us over the next
few hours, don't bother mailing me.  We're switching file
servers and I'm up to my neck in alligators.

sources has been up for just under 3 days and the machine that hosts
the wiki has been up for a little under 10 days, so I think you're
seeing problems with network connectivity.

When sources or the wiki appear to be down, try

	ip/traceroute sources.cs.bell-labs.com
	ip/traceroute outside.cs.bell-labs.com

which should suggest where the problem is.

FYI, sources and the wiki have been intermittently down most of the
day (when I started typing this email the wiki was down, seems to be
back up right now, but the web interface to sources is down now, and I
have had trouble accessing sources over 9p all day).

P.S.: Thanks to people in irc for reporting and confirming the issues.

I hadn't looked into this idea much beyond a moment of curiosity...  Sounds
like you've thought it out quite a bit though :-)

once I get my plan 9 box back up and healthy (and possibly add to the ranks
in my home network) I'd be very interested in taking a look.

You can't just throw a whole arena into an S3 file, since the S3 API
doesn't support seeking within files.

On the other hand, an S3 bucket is essentially a big hash table, and
so is venti. So I opted for the simple approach of storing the blocks
themselves in S3. Given that, a local index doesn't help much. A local
bloom filter probably would help, but for now my server is stateless
(aside from cache).

Right now the server supports the basic venti api, but it falls over
if anything goes wrong on the connection. Once I make it more robust,
I'll put it in contrib for interested parties.

Venti arenas stored on S3, with locally hosted indexes?

It's still up, at least when I try it from home.

What URL are you trying?

I think we may have had the same idea. And I have code, too.

And I just had a really evil idea involving Amazon's S3 storage service...
