This occurs when your preferred DNS server stops responding, or is no longer available, presumably due to your router.
When you already have a connection with another server/computer during this event, it is called "phantom internet", or internet remaining that might soon fade away due to packet loss or new requests, since new requests (usually) attempt to resolve a hostname from the unavailable DNS. Similar to phantom pain.
Person 1: My internet had an outage last night.
Person 2: Ah, that sucks.
Person 1: Luckily I had some phantom internet to finish my ongoing match!

Get the Phantom internet mug.
A person who only appears on the internet very rarely much to the chagrin of their friends who wish they were around more to absorb their awesomeness.
