Dear Customers,
currently we have confirmed problems from Telecom Italia (fiber-cuts in France and Milano, Italy), DTAG (did not get response so far) & T-Mobile and AT&T. No ETA was given so far, but the problems seem to be massive and not only in Italy, Germany, Austria and France, but also noticeable in Greece and other European countries.
We will keep you updated and post as soon as there are updates regarding this issue. We are working for you and doing everything possible to solve the problem ASAP.
