Yeah, it may be extended because the entire database of AIOU is not working anymore. If the condition still persists tomorrow then it is expected the date of admission to be extended.
Keep checking the website of AIOU, when it loads properly then immediately apply and download your challan. As there is a much load of users over the website that’s why it is not showing. It is also because of the corrupt database because “Resources can not be found” this is the error when a user opens admission form online, so it is a fault from University Side not from students. That’s why if the university can not handle this till tomorrow then the date of admission will be extended.
If you have any other questions then do not hesitate to ask.
