UF will test its emergency message system at noon today with hopes of a smoother run than last time.
In a summer test, it took more than an hour for some people to receive text messages on their phones.
Kenneth Allen, UF's emergency management coordinator, said that needs to change.
"The results last time were unacceptable to the university, and the vendor agrees with that," Allen said, referring to ConnectED, which handles UF's text messaging service.
He said the system was tweaked after the last test, and UF expects messages to be received in a matter of minutes this time.
In previous tests, it has taken between five and six minutes for texts to be sent.
Today, UF will send texts and e-mails to about 65,000 students and employees.
Notices will also be posted on UF's Twitter and Facebook pages, directing people to the UF Web site.
Allen said everyone is encouraged to save the number 23177 to their contact lists as "UFAlert" so they can recognize the messages easily in the future.
He also said UF stands by its decision not to send an emergency message after last week's scare at the Reitz Union parking garage.
