Christmas is supposed to be a time for family, but it seems many people up and down the UK will spend at least part of the day glued to a screen using their broadband this year - and for many, not having access to a fast connection could seriously spoil their day.
This is according to research from broadband provider Zen Internet, which found that six out of ten Brits say their Christmas Day celebrations would be harmed if their internet connection was to go down.
What's more, nearly one in three (28 per cent) said it would ruin their day.
Zen noted that this may not be surprising, as for many people, a good connection will be essential if they are trying out new gadgets or turning to streaming services in order to avoid Christmas TV.
Indeed, if families are gathering for the day, there may be extra pressure on a home's broadband to perform if many users are all trying to get online at the same time to stream movies, play their new online games or share pictures of their gifts on social media.
Richard Tang, Chairman and Founder of Zen, said: "With so many new devices set to be connected to the web this festive season, testing the internet connection is now as vital in preparing for the big day as checking whether batteries are included and getting the dinner timings right."
The most commonly-used internet services on Christmas Day are set to be social media sites, with nearly four out of ten respondents (37 per cent) saying they would miss these if they suffered an outage.
This was followed by streaming TV or music sites (24 per cent), video calling services (17 per cent) and gaming (12 per cent).
More than one in ten people will even be looking to get a head start on the Boxing Day sales, with 11 per cent saying they would miss online shopping if they weren't able to access the internet on Christmas Day.
