Exporting quotes is very slow today - why?

Exporting quotes is very slow today - why?

Is there something going on behind the scenes in Zoho CRM today that would be making my exporting of quotes much slower than normal today?

Lately I've been noticing that Zoho CRM runs slow during the day - is this because you are running updates to the software during the working day.  Please - can this be done at night time so that it doesn't effect our sales productivity during the working day???

Many thanks in advance!
