I use blogger.com to host and manage this blog. It appears to be having trouble tonight. I wrote a post at 8:30pm and just after I published it Blogger seemed to go down. I was unable to log in or check any blogger hosted site until 12:30am. However it does appear to have come back for a while around 10pm because my earlier post was added to Irish Blogs and Bloglines at that time.
Update: Yup there was an unscheduled outage last night, they say it was only 15 minutes but I'm sure it was longer. It's all back now. You can check the status of blogger at http://status.blogger.com/. (Ironically hosted on blogger so when blogger goes down its status site goes down as well :-) )
