I am fifty years old and have looked at the night sky for as long as I can rememeber with hope that some day I would have the opportunity to look back...

Weekly Outage and Initial Catch Up
Every Tuesday morning (Pacific time) we begin a five hour data distribution outage for database and systems maintenance. The upload/download servers will be offline during this time. Afterwards you may experience connectivity issues for several more hours as the servers catch up with demand.

Revised scale of significance of ET detection published.
A group of SETI astronomers led by Duncan Forgan, and including myself and BSRC director Andrew Siemion, has published a revised version of the Rio Scale. The Rio Scale is designed to predict the public impact a signal would have, like the Richter scale does for earthquakes. The prior version of the Rio scale, in addition to being rarely used, tended to overestimate the impact of low quality or low significance reports of detection.

Now all we have to do is convince other SETI astronomers and the press to use it.

There is a related article at GeekWire.

A calculator for Rio 2.0 scores in now available here.

Dropped packets
The UC data center switched over to a new firewall this morning. Since then packets into and out of the data center have been suffering drops. The Data Center staff is debugging the problem, we'll probably be dropping packets until it's resolved.

Unexplained database slowness
The database has gotten hung up a couple of times with slow queries. I've restarted it once and that seems to have helped. It'll take several hours to be sure.

If that didn't solve the problem, it probably means the index the server uses to choose workunits to send has gotten corrupted. If I need to rebuild it, we'll probably be down most of tomorrow while I do so.
