Planned Downtime @ 2018-04-21 00:00:00 GMT.
« on: April 19, 2018, 10:34:08 pm »
I will be moving the forums and website over to the new cluster at 2018-04-21 00:00:00 GMT.
Unfortunately due to the huge jump software versions this can not be done without causing some downtime.

The forums should not be down for any longer then an hour provided everything goes OK.
If it does take longer please be patient as we will be working to restore operations as fast as possible.

Part of this migration includes upgrading fully to InnoDB tables on the Barracuda engine, as well as moving to utf8mb4 collation.

Leading up to the move I will not be able to answer questions as I will be preparing so that everything goes smoothly.

Forums are now working again, other areas of the site are still to be completed.

Please hold off reporting any issues until then.

Does this mean that the UTF8 support people have been complaining about for a long time is now solved?

Not sure if I'm suffering from bias but the site seems quite a bit faster to me. :clap:

It should be quite a bit faster again now, the reverse proxy via the old server was just removed.

It should be, the following seems to indicate so :)

Seems database fail over isn't working yet... there may be several short outages while I correct this.

The initial page load is MUCH faster than before  :-+
And I wasn't complaining about the speed of the old server

Had to shoot and run just when gnif pulled the server down and not long been back.
First impressions it is a wee bit faster now.
Thanks Dave and gnif for bravely taking this step forward.  :clap:

Database failover now working, but something wrong with recovery, investigating.

I don't know that it's a "problem" as such - just a size limitation.

At random, still getting "500 Internal Server Error nginx/1.10.3" message, and a refresh cleared it out. Still fast though.

Does this mean that the UTF8 support people have been complaining about for a long time is now solved?

It is indeed, we can now use such advanced symbols as Ω rather than trying to use something ugly like  \$\Omega\$,

Expected, I am still performing server tuning. Unfortunately all the prep work int the world doesn't prepare you for real world workloads.
