Well, I was one of those customers and given just how little Severn Trent seemed to know about the incident and how it happened it made me wonder too.
After 8 hours there was still much confusion. I saw them doing what looked to me as pumping out a water tower into a long like of waiting tankers the next day.
When I was down getting my 4 litres of free water (generous or what!) We asked the ST woman there why we couldn't shower in it and she said it's chlorine and it's way stronger in concentration that you'd get at the swimming baths. (She really couldn't stress just how much we really shouldn't use it to even wash hands). So if something looked like a computer error or hack this is a likely candidate.
Then again, could just be coincidence. Guess we will never know!
