Hello there, @CinziaForasiepi ...
You are always welcome to check the status of Canvas by going to:
Instructure Status
On this page, there are two other areas to look at:
- At the top of the page, you'll find a link to view the uptime of your school's own Canvas environment.
- At the bottom of the page, you'll find a link to view the "Incident History".
Have you checked with your ISP (Internet Service Provider) to see if there have been any issues reported recently within the time frames you've reported here? You might want to check with them.
If you are still having issues, you could reach out to Canvas Support to see if they have any suggestions:
How do I get help with Canvas as an instructor?
Hopefully there are some ideas here that will help. Keep us posted here in the Community...thanks!
