Of course, I do not mean current s3 replication problems. The issue is that the replag value was too unstable during last period of time after new array has been plugged in.<br><br>The reason I&#39;m asking is that according to original River&#39;s post roots are participating decision making for hw upgrades. So, the point here is do we really need to split s1 and s3 on different servers or there is an ability to speedup yarrow for better replication.<br>

 <br>Another point is that currently the replication problems are mainly due<br> to problems caused by the main Wikimedia servers. Replication usually<br> works fine until something happens on the main servers (such as<br>
 masters\slaves being switched or binlogs deleted) then everything<br> breaks. Such problems are difficult to combat, presumably what is needed<br> is better communication between the toolserver and main server teams --<br>
