server"

Bugzilla is not reliable enough for effectual work, I estimate 5% ... 10% of my
connections will be not successful, but end with

Probably it's enough to find out what cron jobs run on that server and schedule
the Bugzilla backups a couple hours earlier, so that it will be less annoying
to Europeans. Or find a way to run them so that they don't cause an
interruption of service at all!

Good news: Tony Stevenson told me that it's indeed a backup issue and that he
is planning some changes (move SQL DB from the local host to the central DB
server) what should solve the problem.

For the record: I setup a bot 2 months ago that will retrieve a Bugzilla page
every 10 minutes. Here is the record of all failed requests. I never got the
502 error (explanations below). Hours are Central European Time (GMT+1).

So: there is a brief interruption on 4 December and occasional truncated/empty
pages at midnight GMT.
This means that probably we should check authenticated access, since anonymous
access (my test) is almost always working. I confirm that, in the same time
frame, I've seen the 502 error as authenticated user in the European early
morning.

CONFIRMED due to comment 1
@Rob:
Still a problem, more or less 7:45 UTC every day all Apache Bugzillas for
particular projects (Jira, AOO, SpamAssassin) are unavailable for a while.
<https://issues.apache.org/> seems not affected.

So indeed that bot access must be different to "real life" access. For me that
problem appears precise as by a swisswatch every morning.
If there are access statistics of course it might be some improvement to move
backup or whatever to a minimum access time. But that would be a poor solution
- Were is the Wikipedia minimum access time where they bother users with
downtimes?

Yes, everytime in the morning between 9 and 11 Clock European Timezone. I
beleve this is the backup system.

Well, I'll take this one and will discuss that problem with Apache
Infrastructure team.

At least the visible problem with every morning blocked BZ has been solved
since SQL DB has been moved.
So I close this one.

I didn't write it explicitly above, but the fact that anonymous access has
virtually no interruptions is easily explained by caching.
