I want to be sure that no one confuses my blogs and Twitter accounts that access the FEMA IPAWS Production Public Alert Feed as official FEMA outlets. They are not. I am not paid by FEMA to run them. I do have an MOA with FEMA to access the production Public Alert Feed. The blogs are my own separate work. The posts are run from my non-government, personally owned, computer to a blog host that is also not run by, or contracted to, the U.S. Government.
One other note: The example blogs are actually subject to downtime due to local power failure ( my UPS lasts about 2 hours). I have a backup on a thumb drive, so I can restart it from any machine that I can get to with access to the internet. I have a laptop ready. Not your classic active-active redundant operational capability, but the best I can do as a one man band. If I were to set one of these blogs up for a customer, it would be up to that customer to determine both retrieval customization and what level of resiliency they wish to have (and pay for). All levels are possible.
