E&B are proposing overnight electrical works on the George Square HV ring, and are canvassing for dates which should be avoided, Exam dates are supposed to be already protected. There's no indication as to roughly when they're thinking about.
core3 have been done.
core0 was originally scheduled for this afternoon, but has
been postponed (probably to Tuesday 4th December) to avoid potential
DHCP-specified routing was moved to
on Monday morning first thing, to allow time for existing leases to expire.
We'll just leave that in place until the upgrade actually happens.
RDISC-based routing will be moved to
core1 at lunch time
one the day, as this only takes a few seconds
for clients to adjust; likewise for IPv6 RAs. The spanning-tree will also
be rebalanced at that time ahead of replacing what is
the usual root bridge. See the
Finally will be
atc0 at a date to be arranged, but almost
certainly now in the new year.
As previously mentioned
we intend adjusting our OSPFv2 costs in line with our OSPFv3 costs, so that
internal IPv4 traffic always prefers to hop through two core switches
rather than one edge router. With the replacement of
we'll take the first step in this process.
We are, of course, making sure that our instructions and processes are up to date and accurate, fixing anything we spot as we go along.
We had an instance of the "Crazy Console AKA Brown Effect" on
hazlewood on Saturday, which came to our attention as a result
of errors from cron jobs. Holding down RETURN on the console
for a long time on Monday eventually unbunged it, though we rebooted
afterwards anyway to clear up some lingering oddities. Some observations:
systemdto reboot until the console was completely unbunged.
As we've remarked before, this all feels uncomfortably fragile.
As part of the ongoing "account tidying" project, we have deleted a further 2439 user accounts.
We still have three of these to do. Each one takes so long that it's only really possible to do one a morning and still stay reasonably off-peak.
