12 August 2017: Reboot for patching Xen Security Advisories (XSAs)

This is a past/expired downtime notification. The downtimes specified below have been completed, and remarks/results are given below as well.

Unless otherwise noted, all dates and times are given in Coordinated Universal Time (UTC), with time in 24-hour notation.

Update: The downtime was completed on-time and without issues at 03:49 UTC.

Update 2: It looks like the XSAs patched in this round of reboots were XSAs 226 through 230 (you can find the full list here), with analysis by the QubesOS team.

Woah.  Déjà vu, anyone?

The Xen development team has released several critical and so far undisclosed Xen Security Advisories (XSAs) (is it just me, or does it feel like this has been happening a lot recently?), and as such, Linode (LizardNet’s provider) will be performing emergency maintenance on all of their Xen hosts. LizardNet’s sole Xen system, phazon.fastlizard4.org, will be rebooted as part of the endeavour to patch the Xen vulnerabilities before the public disclosure time of 15 August 2017. (More information can be found on the Linode status blog here.)

This blog post will be updated upon downtime completion, and when the relevant XSAs are made public.

The following server and services will experience downtime:
