Hi there, I am not sure if this is an isolated case but I have been having late notifications of student postings for the past 3-4 weeks. Students have posted up their comments and I only received the notifications by email 5-7 days afterwards. Could be my institution server issue? There wasn't any lag previously since Sept. 

To be specific, these lags were only for the Basic Research Methods in Health Science, class USM PPSK Sem 1 2018/19. It's a private class (for now). 

Thanks
