In celebration of the new version of the Alert Banner launching today, it’s time to give an overview of what’s new. If you did not know there was a banner please read about it. Basically there is a system in place that can deliver a dynamic notification on to your website if there is some sort of wide-spread emergency. If there is a reason to suspend operations, for example, we want to get the message out as widely as possible.
Now as better, cloud-based solutions are available it’s time for a change. The new system is powered by wordpress.com and based off their API. The biggest win is the reliability and the decreased cost. Instead of a dedicated server, which costs regardless traffic levels, we have a minimal yearly cost. The API allows a JSON output similar to what is currently used, with a bonus of finally being able to open it up to the greater community.
Instead of a potential one-minute delay, the banner is now instantaneous. There is a :30 second local cache to avoid hammering the service. The test banner is also callable via a #uwalert-<color> hash tag instead of including changing out the url to the script. The html behind the banner is also fully responsive and displays nicely on mobile. Please visit the toolkit page and read the detailed documentation if you haven’t yet. Otherwise, enjoy!
