||Do we really need a new word for this?
When you go to the store and there's too many people, you have to wait a long time. We say the store was "busy" or "crowded." Often when demand exceeds supply, we call it "overloaded," or even "swamped." There are dozens of words that appropriately describe what happens when the freeway has too many cars on it or there are too many people heading for the exits at once, or when a server's capacity is too small for the current traffic level. A new phrase for this? Nay, we can do just fine with the phrases we already have.
I shall now quote the quintessential American philosopher Henry David Thoreau: ...er, well, no I don't really feel like looking stuff up just now. Use your IMAGINATION for once people! Remember that? The IMAGINATION? People used THAT back in the days before TV and computers did it all for you. So anyway, just imagine an appropriate pithy phrase from Henry David Throeau, quintessential American philosopher, adomnishing you not to invent a new word or phrase every time some new technology creates a "new" situation.
If you think about it, new technology failing to handle the load it is given is an old situation indeed, and not at all a thing we need to invent new language to handle.
I do, I do, I do
