Great Britain earned the chance to fight for a place in the 2022 Billie Jean King Cup Finals with a 3-1 victory in their play-off tie against Mexico.
Britain, who have lost all four of the World Group II play-off ties they've played in the last decade, broke new ground with a fine team performance at the National Tennis Centre in Roehampton.
Katie Boulter once again produced some of her best tennis in national colours, taking wins in both her singles contests, and her 6-4 6-1 win over Giuliana Olmos wrapped it all up.
Team captain Anne Keothavong said: "It's a special feeling. To get a win at this stage of the competition is great.
"We haven't been in this position too many times as a team so we've got to take it.
"We came in with high expectations and the players delivered, I'm proud of how they got the job done.
"We had to be good and we give respect and credit to Mexico for coming here and giving it their best shot. They were the underdogs and the pressure was on us.
"We've had a good team spirit and the players have really got behind each other this week."
Leicester-born Boulter has won seven of her eight rubbers in the event, mostly in its former guise as the Fed Cup, and thrived in the heat of battle once again.
She beat world No. 285 Marcela Zacarias 7-5 6-0 on opening day to get the ball rolling and Rio Olympian Heather Watson matched that almost exactly in her contest.
Watson saw off a spirited Olmos 7-5 6-1 to take her 29th career victory in the tournament, giving Britain a 2-0 overnight lead.
Boulter then did the job in straight sets to mean the final doubles contest was not required.
"It was a really, really tough match," said the 24-year-old.
"I knew I needed to keep calm and bring my best tennis. I felt confident going into it and the second set was a lot stronger.
"I knew she'd come in fighting and I had to bring more than that. We both played really well, I got myself over the line and I'm proud of the composure I showed.
"It's a huge moment for us and I'm proud of how we've played."
The team's will have the chance to fight for the right to be one of the 12 world-leading nations who contest the 2022 Finals.
