What percentage of the space used for artifacts is actually builds<br>
that are used for mozregression vs other stuff (like debug builds)? Is<br>
there a way that we could somehow have different expiraries for the<br>

builds seems very generous but 8 months for builds for mozregression<br>
seems stingy.<br></blockquote><div><br></div><div>Keep in mind this is only temporary, with every passing day we approach a full year's worth of builds again. As a longer term solution to this particular problem, I wonder if we can get mozregression to farm out missing builds on try.. then there would be no limit to how far back it could go.<br></div><div> </div><div><br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
