Recent move followup

As you all know, the sites moved to a new location and even onto a new platform. During the move the platform changed and that led to some unexpected issues.

  1. Temporary SSL Certificate issue: Some people, namely those on IE7 and IE8 and a few on Android phones were getting an error about untrusted security certificate when they try to log into the site or use any secure pages. It turned out to be a configuration problem and it’s fixed (needed to configure and specify unique IP addresses for each secure domain).
  2. Kindle eBooks didn’t work: Due to the platform change new updated binaries for the kindlegen software from amazon were needed.
  3. Zip files issue: Some members reported inability to expand zipped archives generated on the new servers. I couldn’t duplicate the issue, but nonetheless, changed the zip archive generation algorithm to use my own hand-rolled zipping solution. Hopefully that solves it. I haven’t heard any complaints since the change.
  4. Slow site during peak time: The new set up doesn’t handle text search well. I’m not sure if it’s a hardware problem (not enough processor bandwidth) or a software configuration problem. Whatever it is, I couldn’t find a solution quickly. I’ve moved text search to a small server that I had lying around. It’s slow but for now it does the job and now text search works without affecting the main database server.
    I’m still working on this one. I will be installing a different indexing software (something more efficient than MySQL’s own built in full text index) and rewriting the text search scripts to use the new software. Hopefully that would solve it.

If there are any outstanding issues that you’ve encountered, let me know. You can leave a comment here or send me a message directly through one of the sites’ webmaster forms.
