During a widespread outage, waiting is usually all you can do — the fault lies with the provider, not with your device. Still, a few things are worth checking:

• Unplug your router for 30 seconds and restart it — this fixes local glitches.
• Check whether neighbours or colleagues with the same provider are affected too.
• Mobile: briefly toggle flight mode on and off so your device re-registers with the network.
• 1&1 outage hotline: 0721 96 00 (often overloaded during major outages).
• Report your outage here on störung.online — the more reports, the clearer the picture for everyone.

Report numbers are back to normal. If you are still having problems, restart your router or device — after major outages this often helps re-establish the connection. If the problems persist, contact 1&1 support.
