Hello, these things always happen on fridays at 5 p.m. I know it is down, I can't do anything for it until the people that are maintaining the web site at UQAM are back to work on monday...#$%#$... The web site I have with all the archives from OEIS, the inverter and my home page is a special permission from uqam. I can't ask them to be there on weekends just for me... Everything should go back to normal soon. Simon plouffe
