INSTANT messaging service WhatsApp has set a new company record for the number of messages handled in a single day, just weeks after being purchased by Facebook.
In a tweet sent from the company's official Twitter account, the messaging service announced that in a 24 hour period more than 64 billion messages were handled.
This breaks down into 20 billion sent messages and 44 billion received according to the tweet. The figures differ due to the group messaging setting in the app which counts a message sent to a group as one sent item, but is counted as received by each individual in the group.
A year ago, WhatsApp's daily message traffic was around 27 billion a day; highlighting a significant increase in traffic.
In February, social media giant Facebook announced that it had acquired WhatsApp in a deal worth up to 19 billion dollars, but this sparked concerns about privacy issues among WhatsApp users.
In order to quash the concern, WhatsApp CEO Jan Koum posted on the company's blog last month, reiterating the Facebook partnership would not affect user privacy.
"If partnering with Facebook meant that we had to change our values, we wouldn't have done it. Instead, we are forming a partnership that would allow us to continue operating independently and autonomously," he said. "Our fundamental values and beliefs will not change. Our principles will not change. Everything that has made WhatsApp the leader in personal messaging will still be in place."
It appears that statement has been taken on board, as this latest record highlights continuing growth of the service, and follows on from the announcement earlier this year that the app had passed 465 million monthly active users, higher that Twitter.
Today however, there have been increased reports of problems with the WhatsApp service, with the website DownDetector.com, which monitors web problems, reporting that the number of users reporting issues with the app jumped by more than 2,000 in less than two hours. Users have also been posting error messages from WhatsApp to other social networks.
