Hello,
Here's some information that those of you using your VPSes to handle
email may be interested in:
https://github.com/antibodyMX/communicado
If you're not interested in receiving such emails from Communicado
then the information there should help you, and please do consider
contributing to the effort if you're able.
Cheers,
Andy

Hi,
As you may be aware, massive distributed denial of service attacks
have been mounted over the last couple of weeks by sending forged
administrative queries to public NTP servers.
A favourite query in use is "monlist", which results in a constant
stream of data being returned from the NTP server to the victim
host.
While we have no evidence that any BitFolk VPS has so far been used
in such an attack, we are going to take some pre-emptive action to
minimise the risk.
As there is no need to allow these administrative queries from the
entire Internet, we now require these to be disabled by default and
only allowed from specified trusted hosts. This has always been the
configuration provided to you on provisioning of your VPS, so only
those who have changed their ntpd configuration would have
re-enabled administrative queries.
Disabling administrative queries is normally achieved by using the
"noquery" option in the "restrict" lines. This setting does not
disallow time synchronisation.
For more information please see:

Cheers,
Andy

Hi,
Unfortunately due to what looks like a kernel bug, sol.bitfolk.com
has got stuck in a state where VPSes cannot be booted. I therefore
need to reboot it as a matter of urgency, so those with VPSes hosted
on sol are shortly going to see a clean shutdown and boot.
I apologise for the disruption and I hope to be able to give more
information later. I will follow up again when all customr VPSes
are known to have booted.
Cheers,
Andy
