Yes, although their first ad break wasn't a real ad break, it was a spoof by The Big Breakfast
I was watching C4 that night (in London) and there was some very obvious picture disturbance on and soon after midnight - I remember people I was with at the time commenting on the disruption. The various changes would have all taken place at midnight, as I say there was a jump a few minutes after midnight that seemed to co-incide with Teletext coming on air
There were a number on important changes that night.
ITV and C4: The switch from Oracle to Teletext Ltd. The programme companies had nothing to do with Teletext.
The insertion points were at (still are) each main transmitter, so at midnight NTL (ex IBA now Arqiva) engineers had to patch an inserter into the video path at the appropriate transmitter sites.
I saw a very slight glitch a few seconds after midnight on Meridian, that was the exact point at which the Teletext data stream appeared..
C4's contract with BT changed at midnight, out went the analogue SHF BT links, and local ends via the ITV companies, and in came the BT fibre optic system, feeding main transmitters directly serving the LEMNUS macro regions. I have no detail how the changeover was achieved, but the interruptions reported in this thread were almost certainly due to that switchover. There'd have been work required at C4 HFR, and at about 25 transmitter sites.
I've watched Channel 4's countdown-to-midnight 1993 programme - it was a Big Breakfast special, with plenty of reference to C4's new independence (I'm pretty sure they referred to their "first" advert break).

There was no obvious switch. Perhaps the actual switch didn't happen until after closedown that night - the only difference between midnight and closedown was the ITV regions didn't 'opt out' at the breaks? Maybe they included a couple of seconds of black at the end of the last break and that was the point the switch was made (I'm guess switching black to black would not be quite so visible)?
