I've just created two new external storage clusters, which are now the default destinations for all writes to pmtpa wikis. The masters are srv83 (cluster6) and srv86 (cluster7). I don't know what you're doing about external storage replication, and I couldn't find any documentation on it, so I don't know if this affects the toolserver or not. I'm just sending this note in case someone here needs to reconfigure something.
Here is current external storage configuration in full:
$wgExternalServers = array( 'cluster1' => array( array( 'host'=> 'srv30', 'load' =>1)+$externalTemplate , // Master array( 'host'=> 'srv28', 'load' =>1)+$externalTemplate , array( 'host'=> 'srv29', 'load' =>1)+$externalTemplate , ), 'cluster2' => array( array( 'host'=> 'srv27', 'load' =>1)+$externalTemplate , // Master array( 'host'=> 'srv25', 'load' =>1)+$externalTemplate , array( 'host'=> 'srv24', 'load' =>1)+$externalTemplate , ), 'cluster3' => array( array( 'host'=> 'srv34', 'load' =>1)+$externalTemplate , // Master array( 'host'=> 'srv33', 'load' =>1)+$externalTemplate , array( 'host'=> 'srv32', 'load' =>1)+$externalTemplate , array( 'host'=> 'srv36', 'load' =>1)+$externalTemplate , ), 'cluster4' => array( array( 'host'=> 'srv73', 'load' => 1 ) + $externalTemplate, // Master array( 'host'=> 'srv72', 'load' => 1 ) + $externalTemplate, array( 'host'=> 'srv71', 'load' => 1 ) + $externalTemplate, ), 'cluster5' => array( array( 'host'=> 'srv76', 'load' => 1 ) + $externalTemplate, // Master array( 'host'=> 'srv75', 'load' => 1 ) + $externalTemplate, array( 'host'=> 'srv74', 'load' => 1 ) + $externalTemplate, ), 'cluster6' => array( array( 'host'=> 'srv83', 'load' => 1 ) + $externalTemplate, // Master array( 'host'=> 'srv82', 'load' => 1 ) + $externalTemplate, array( 'host'=> 'srv81', 'load' => 1 ) + $externalTemplate, ), 'cluster7' => array( array( 'host'=> 'srv86', 'load' => 1 ) + $externalTemplate, // Master array( 'host'=> 'srv85', 'load' => 1 ) + $externalTemplate, array( 'host'=> 'srv84', 'load' => 1 ) + $externalTemplate, ), );
