A simple service for checking the availability of a site without entering a captcha?

Question

Computer networks

I used to use downforeveryoneorjustme.com, but it has switched to a trickier interface, making it harder to use.
Does anyone know how to solve the problem? Or a similar service for checking the availability of a site without entering a captcha? Something like example.com/?site=testsite.ru - and the answer is yes/no.
You can only use JS and ajax - load the site and parse, otherwise nothing.
PS Don't know what tags would fit this question.

Answer 1

Often you have to evaluate the availability of your own projects. And standard services, such as ping sites, are indispensable here. You need to evaluate the availability, the work of php, database, etc. That is, the site can work (static), and the base is covered. Or php will be covered, and the content will be cached on the server. Lots of options.
Time intervals are different. All results must be stored.
Well, for example, to present to the hoster that the site hung for an hour due to its lags (from and to). Hosters are different. (
I had to write my own "page" on the site being checked. And my own system on another hosting, which ran the check script via cron. And the script accessed the "page" on the site being checked and received an answer - ok or error (simplified).
But closer to question.
I don't know the system. But writing such a php script, ala ping a site, is quite possible in 20 minutes.
Need hosting with php mysql and cron. And free hosting with cron is extremely difficult to find.
And for a fee, all of the above is available for everyone.
This is how it is done for projects where uptime is important and for which there are constant requests.
Not a service, of course, but he is his own boss and is not limited in anything.
