Hello,
Unfortunately some serious security bugs have been discovered in the
Xen hypervisor and fixes for these have now been pre-disclosed, with
an embargo that ends at 1200Z on 9 June 2022.
As a result we will need to apply these fixes and reboot everything
before that time. We are likely to do this in the early hours of the
morning UK time, on 7, 8 and 9 June.
In the next few days individual emails will be sent out confirming
to you which hour long maintenance window your services are in. The
times will be in UTC; please note that UK is currently observing
daylight savings and as such is currently at UTC+1. We expect the
work to take between 15 and 30 minutes per bare metal host.
If you have opted in to suspend and restore¹ then your VM will be
suspended to storage and restored again after the host it is on is
rebooted. Otherwise your VM will be cleanly shut down and booted
again later.
If you cannot tolerate the downtime then please contact
support(a)bitfolk.com. We may be able to migrate² you to
already-patched hardware before the maintenance is scheduled for
your host. You can expect a few tens of seconds of pausing in that
case. This process uses suspend&restore so has the same caveats.
Cheers,
Andy

Hi,
As requested this check is now enabled for all customer DNS zones in
the secondary DNS service. The alert will look like this:
https://tools.bitfolk.com/wiki/Secondary_DNS_service#Zone_serials_match
If you receive it then the first thing to do is to check your
nameserver's logs as it will normally be due to an issue that (only)
you can fix yourself.
Cheers,
Andy

I do like the sound of that, Andy (Smith).
