Here you go! An example of when ITV Schools on C4 went off air for most of the morning.
(Thanks to SiCo)
OK, just to clarify a few things.
Schools programmes were broadcast on Channel 4 a couple of times during Summer 1987, and these were all played out by Channel 4, who had copies of the current slide, clock (on video) and the programmes.
I can't actually view the breakdown footage Ben posted, but I know it is my own recording and dates from no earlier than 1989 (probably Spring 1989). Schools programmes fell off the air, we saw a blank screen and I think temporarily the 'blue screen of death' from the local transmitter. Channel 4 then showed the '30th Anniversary (surgery)' slide with the 'schools programmes will resume as soon as possible' caption superimposed, this was then replaced by a still '4' symbol, then a plain black screen with 'apologies for the loss of schools programmes - channel 4 programmes will begin shortly', and a classical testcard tape then faded up. [All those captions were shown that morning, but I may be remembering the order incorrectly - Ben's upload will clarify].
Anyway, my real point is that the 1987 '30th Anniversary' slide was shown again during that breakdown in c. 1989. It's the only example I've seen of a breakdown during the 1987-93 ITV Schools on Four era. I don't know if channel 4 had any standby 'crash' sequence (such as an extended roto) - either they didn't, or the problem that morning was so serious that even that sequence couldn't be put to air. It was a total loss of service from mid-morning (10.30ish) until 12 noon. I assume the 1987 slide was the first suitable thing they could put to air (or maybe it was intentionally kept nearby for such occasions) - proof, if we need it, that Channel 4 did play out the junctions and programmes on the two occasions they were shown on that channel in 1987.
EDITED TO ADD: I wonder what S4C did that morning? I assume they lost the Channel 4 feed of programmes, but we're probably in a position to put their own apology caption to air - maybe even with a live announcement? - and if they were due to opt out and show their own schools programmes at any point during the breakdown, these may still have made it to air.
