Hi all,
I was working on my VM about an hour ago, and suddenly lost all
connection to
my VM on macallan.bitfolk.com
the recovery machine .console.bitfolk.com
the bitfolk website.
All back now.
It was not local to here (Bangkok) because I could reach every other
site I tried.
I would like to know what happened?
I'm guessing something got to hot on this hot day in London, and let out
its magic smoke.
Regards
Ian

Okay, so you lost connectivity to the entirety of BitFolk, possibly
more.
Since BitFolk is in the same AS as Jump and shares network fate, you
probably lost connectivity to Jump as well. In future you can
confirm that by trying to reach the web site at
https://www.jump.net.uk/
If that was the case and we'd caught this at the time, then I'd be
asking Jump to look into that. But we didn't notice anything on our
end, and have no other reports, so it's not really worth me saying,
"someone on the Internet couldn't reach Jump's network but now they
can".
What IP address were you coming from? I can look at the routing now,
and see if there was any disturbance known around the time you
mention (~10:50 UTC?)

Didn't notice anything here either, so was likely something way in
between.

It's mostly impossible to tell without records of traceroutes or
similar at the time of the outage. Did you happen to do any?
"traceroute" is okay, but "mtr -Zn [host]" is often more
interesting.
I'm guessing something got to hot on this hot day
in London, and let out its
magic smoke.
Or indeed any device between London and Bangkok! In theory things
are supposed to reroute quickly but doesn't always happen, depending
on the nature of the failure.
All I can say is it wasn't something directly under BitFolk's or
Jump's control / knowledge.
Cheers,
Andy

Hi Andy,
Take a look at https://photos.app.goo.gl/C3J4VFvWg81iWKfr7
Some machines appear to be dropping things, like a new waitress in
too-high heals :)

I had another break a while later. Oh well. Things happen.
Cheers.

If you use -r (report) in conjunction with -c 50 (count of 50) then
you'll get output you can copy and paste as plain text. So:

(there'll be no output until the 50 iterations are done)
I took a guess at an IP close by you from your photo, but it would
be better if you could work out your own public IP by going to
whatismyip.com or something.

Well, in your photo and in my output the packets do make it to the
end without loss, and that's the most important thing. It's common
for hops in the middle to reject or drop packets directly to them.
The output above and your photo look pretty normal for what it is.
There's some asymmetric routing going on as well (normal): for you
to Jump goes through True / Asianet and then Hurricane Electric, but
from Jump to you goes NTT and then True / Asianet. I can look into
if there were any problems within NTT and HE earlier.
Cheers,
Andy
