Google has stopped providing support for goo.gl URL shortening services since 30th March 2018 onward and google as put a notification on their official website of goo.gl for the same.
from 13th April 2018 only existing customer can able to use goo.gl services and they can see analytics and download reports from the website. However, from 30th March 2019 onward goo.gl will discontinue completely. There will not be any impact on existing created short URLs and they will be continued to redirecting to the original urls.
Now, its a big change that Google going to do in their services and the main reason for the same is that many of the website have their own URL shortening services like Facebook and twitter.
