Glad to see that the issue appears to be resolved, Esploratore. 
Checking the link provided by Nz earlier in this thread, it looks like the issue was resolved about 8 ago (so during the night of Friday).
For everyone, please do give it another try and see how the connection is behaving. If the issue persists on your end, do try to contact your ISP as this would be a routing issue, which is happening outside of our network.
