My ISP upgraded Perl on this server recently and, in doing so, broke MT-Blacklist for this blog (MT-Blacklist is a MoveableType plugin that helps prevent comment spam). After speaking with an admin at my ISP this afternoon, they are not going to be able to fix the problem until Monday (due to the fact that the people who will need to fix the appropriate files are out of the office until then). No worries there, because this isn't a mission-critical thing for me.
However, because this blog has been getting spam-bombed over the past several days and MT-Blacklist isn't not working at the moment, I have temporarily disabled commenting until the problem is fixed.
Just so you know.
