As you may be aware, the mitigations we deployed earlier this year for Meltdown and Spectre were the
best available at the time, but were incomplete. In addition to other changes, we would like to
deploy more complete updates on the host server for whyy.xen.prgmr.com covering Spectre v2/SP2 now
that all the dependencies are available. We are still not aware of any update for Spectre v1.

These updates requires system reboots. We have allocated up to two hours after 2018-05-07 04:00:00
UTC for this maintenance window.

You will receive a credit for this downtime based on how long the service is unavailable. We will
send an email to the account primary and technical contacts when the host server is brought down and
when it is started again.

If this time window does not work for you, we may be able to move your VPS to a different host
server in advance of this window, though depending on disk size the total downtime for this move may
exceed the downtime from staying on the same host server.

You may want to review the grub configuration file /boot/grub/menu.lst (typical, used with pv-grub)
or grub.cfg (with grub2) in advance of this reboot to verify it is sane and has a valid default
entry. You may also wish to verify you are still able to log into the management console
https://wiki.prgmr.com/mediawiki/index.php/Management_Console in advance of the reboot. We will
allow 5 minutes for the VPS to shut down from the time that the shutdown signal is sent before
performing an unclean shutdown. If you are concerned this is not enough time, please contact us or
shut them down yourself 10 minutes prior to the maintenance window.

We will be rebooting internal systems, including billing and the management console, during a two
hour window beginning 2018-04-29 04:00:00 UTC.

If you have any other questions or concerns please contact us.

Regards,
Prgmr.com support
