If there is anything we've learned from watching what happens to the Black Ops 3 servers after a major update, and even a smaller hotfix, it is that there are normally issues.
After most of the Black Ops 3 updates there are server problems where some users cannot play online. There may also be some problems accessing the Black Ops 3 DLC 3 maps. Usually that is ironed out quickly without the need for another update. Be prepared for a few bumps in the 24 hours following the release of the next Black Ops 3 update.
