Hi Peter,

Yep it crapped out again. several times a week at the moment.
Thanks to Thomas for restarting it.

We should make the frontend more resilient to this.

Some ideas:
- Frontend should have a lower timeout
- Maybe tweak the nginx gateway timeout to the smolt backend
- I thought uploading the hardware profile was an async task.
tbh, if it doesn't already it should, start it's own thread
to gather that info, queue it for upload, and upload if / when
smolt is available.

I do have some future plans to rewrite the smolt backend, and
add further useful bits of information then.

fyi i'll be offline until tuesday after about 5pm uk time so
when it wedges again, thomas will need to fix it.

I'll look at adding an irc notification.
