It’s so annoying when you want to access a site or service and it’s down for maintenance. You don’t want to keep clicking refresh yourself indefinitely. But you also don’t want to forget to come back later.
Notify When Up is the solution. This free tool is here as a public service for you and your friends and colleagues to use.
If you need any help, please do get in touch and I’ll do my best to help.
I'm looking to maintain and further develop Notify When Up, so if have any suggestions or feature requests, get in touch!
Best wishes,
The Developer
Bookmarklet for Notify When Up
To make life easier, you can use this bookmarklet to quickly make new checks.
The bookmarklet will grab the address of the page that is down and draft a new check with the URL option already filled in.
This works in most cases. The only case when this bookmarklet doesn’t work is when a domain has just been registered for the first time and isn’t yet resolvable.
We check whether the URL you have asked us to check appears to be accessible from our server in London, UK.
If the web server sends an error code, we consider the website down.
Technically speaking, if the web server sends anything other than a 200 OK header code, we consider the website down.
We also check whether it contains any maintenance messages or offline warnings — and if it does, we consider the website down until those messages disappear.
This domain was first used back in 2008 to serve a similar service to the one we are offering now.
By 2012 the domain was redirecting to alternative service dingitsup.com.
By 2015 the domain was no longer being renewed, which doesn't presently work.
In summer 2018, we took over the domain to reinstate the public service that was originally served here. Harry Fear coded the site in 4 hours on a sunny day in Bologna, Italy.
