We pushed an
update to Flash Player for Red Hat Enterprise Linux Supplementary today, on
a Friday, because it fixed Critical vulnerabilities. But we try not to push
updates on a Friday unless they are critical and already public.
So let's take a look at the most common times and days we push
advisories for Red Hat Enterprise Linux 4, 5, and 6 (including
Supplementary) using a heatmap:
The more advisories pushed for a given date and hour, the darker
that section of the graph is. So the most popular times
for pushing advisories are Tuesdays at 10am and 2pm Eastern US time,
Fridays are pretty light for pushes, and there was nothing
during the weekends. The spread of the graph shows that we push advisories when
they are ready, rather than waiting to a fixed day and time, in order to reduce
the risk to users.
All the data used to create this graph is available as part of
our public metrics.
