When a hotel doesn't have a 24/7 online system like the above companies, booking.com simply relies on the hotel to update their inventory on booking.com's system manually, and then faxes the hotel everytime a reservation comes through. The fax can fail, and so can the minimum wage employees who may or may not be tasked with updating booking.com's systems.
Bottom line is always confirm, and re-confirm when the consequences are great enough to warrant spending time re-confirming. And especially try to deal with the vendor directly, onsite especially. If you make a reservation at a hotel that doesn't have an app that shows your reservation in real time, then call and get the email address of someone who actually works on site, and then email them to confirm your reservation, and so you have something in writing from someone at the hotel.
Some of them will refer you right back to booking.com though if you want to book online, in which case it's probably fine and the hotel uses booking.com directly. Or booking.com sends them a fax or email.
I just confirmed the booking by paying. I shouldn't have my booking cancelled because I didn't respond to an email. We can do better than that.
