Formula One Management and F1's official timekeeper LG have explained the reasons for the timing failure at the end of qualifying for the Hungarian Grand Prix.
Live timing stopped working at the end of the session, and even drivers were unsure about their positions when they climbed out of their cars. FOM said on Sunday after the race that the finish line sensor had failed as a consequence of a broken cable, but that no data had been lost.
"In the closing minutes of the third part of the Formula 1 qualifying session yesterday the finish line sensor suffered a mechanical failure in the form of a damaged cable," said FOM in statement said.
"Standard procedures were followed and the back-up sensor used. Once the verification procedures were complete the full results were published. At no time was any timing data lost."
