I've got nothing to do with the ASSTR site admin but this is what I understand to be the latest announcement from them regarding ongoing site problems.

ASSTR community, As many of you have already discovered, we're having some server issues that are causing site outages at times and an old copy of the web site to appear at other times. These issues are due to our primary web server repeatedly crashing, possibly due to a broken fan that is causing the machine to overheat. Because the server is located in a data center thousands of miles from where any site admin is located, diagnosing the problem and resolving it is easier said than done. We are working to get things back to normal as quickly as possible while at the same time putting together a plan to migrate to a more cloud-based site architecture that should hopefully lessen or eliminate these kinds of problems caused by hardware failures in the future. Thank you for your time and understand. - Rey del Sexo ASSTR Administration
