It wasn't until Toowoomba disappeared underwater on Monday that I thought I should probably see if my house was at risk. I wasn't the only one though; the Brisbane City Council website was suffering under heavy activity and was refusing to load.

What I was looking for was a file I had stumbled across about a month earlier: a suburb flood flag map. That evening I asked Twitter if anyone had the map for my area: New Farm. I eventually discovered I still had it on my drive but, by that stage, others had asked me to let them know if I find it. To help others, I put up a web page on my server on late Tuesday night with the handful of files I was able to find. I then told people on Twitter and Facebook where to find the page and went to bed.
