The misjudgment consisted in choosing edge servers initially. This facility should have been implemented on a mainframe, where adequate availability is a given.
I have serious concerns about the capability of the people running IBMs web infrastructure.
Taking a service down for almost 3 days to do an upgrade is a disgrace. Even your average fairy cake blogger knows they can put their old site in read-only mode while they switch over to the new one.
The z/OS Information Centre was down all day last week. When it is up it's diabolically slow. If they were running edge servers the content would be replicated to a server geographically closer thus giving me a better user experience. I bet
IC is running on some virtualized server in Boulder.
Complaints about and expectations for the availability of the IBM-Support portal have always been unrealistic. They are extrapolations from the complainers' mainframe experience that are inappropriate to a different, much more fragile environment, one in which failures, reboots, and frequent 'quiescences' for maintenance are the norm.
We run several non-mainframe servers with almost zero downtime and only one sysadmin. Almost all serious outages are down
to human error, not hardware failures.
