The blog has been mostly inaccessible for the last hour or so - it was a scaling issue with one of the early things I did in the server code. At the bottom of the page here is a list of referers. I have Smalltalk code that generates that, and it has been running in the same image that serves the blog pages. The problem? Traffic (especially spam traffic) is up - so having a process that read log files, filtered them (in memory) and then spit out the cleansed files to be read by the server was a little too much - each time the log scan code ran, it was slowing the server down - and finally, today, just making it inaccessible.

The answer, of course, is to move that code out of the main server and run it as a cron job - which is what I have to do now.
