Hurray, after four days the D forum is back.

Anyone any idea why it was down so long?

Ok, it wasn't down, but no one could post anything.

Oh, so THAT was why they were so silent. I was unaware of the problem as I hadn't tried posting myself.

An attempt to upgrade the NNTP software to 2.7 from 2.6 caused the problem. Yesterday I suggested to Jan to give up on 2.7 and go back to 2.6, restoring the system from a snapshot.

While this worked, it also meant we lost postings from the time of the backup to when the forum went down.

A related problem surfaced. I use Thunderbird mail as my news reader. It turns out that every attempt to refresh the news articles in Thunderbird caused Thunderbird to corrupt its database of articles. I had to restore that from backup, too.

I've had problems before with TB corrupting its files. It does not have a robust database that can fix itself from errors, so a simple error in the database causes the entire database to become irretrievable. TB also has fragility issues in that when an error happens (like cannot connect to the nntp server) it borks up its database.

The newsgroup server failed, and they couldn't recover it for several days.

The D forums are backed by a usenet NNTP server, which means you can either post via a newsreader, or via the web interface. The reason the forums were still "up" is because the web forum also stores all the historical posts, so you can read what had already been sent, but not send new messages.

Yeah, I've had to unsubscribe and resubscribe, and now I'm downloading all the history again.

Such a pain.

I kind of feel like the reason it is "corrupt" is because the "latest article" id is in the future, so it's not downloading any new messages since they appear to be in the past.

In any case, glad to have this important resource up and running again!

Cloning the installation and testing the upgrade was not possible? (rhetorical question).

There are some postings in the forum missing. I thought the forum has its own message store. After login the forum presented me unsent drafts one of which I could not send because of "No groups" (dotted red box)...
