Just the other day, the cables suspending the telescope finally gave way and the entire assembly came crashing down into the dish, destroying the telescope irreparably, and doing considerable damage to the dish and the towers.
This came after cables had broken earlier (doing initial damage to the dish), and as a result of years and years of poor maintenance, as funding was cut down dramatically. One of the most powerful science instruments ever built, just left to rot, even though it proved itself to be as useful as ever until its last days.
Likely, it will never be rebuilt, as it's cheaper and easier to build (and maintain and upgrade) other kinds of more modern telescopes, though a radio telescope such as the Arecibo had, as I understand, some real advantages over those.
