As there are many advantages of using a VPS there are few disadvantages of using it, You may have to face problems while using VPS hosting plans, VPS maintenance is major issues with many webhosts. As each  each virtual private servers have their own Operating system and software thus the physical webserver will have to look after all operating systems which are used by all VPSes created on master node. Thus if master node gets down or facing some operating system issue all the VPSes created on that node will have to face downtime.
Also if master server node gets down due to hardware failure or system crash then all VPSs would have to face downtime.
Usually there are many VPSes created on master node thus it’s a difficult to manage and maintain master node as it would be having hifi configuration, advance RAID structure, network file system etc… which are somewhat difficult to manage.
Make sure, if you are having a server with reliable host who offer you maximum uptime guarantee then you may not have to face any kind of issue, this doesn’t mean that all VPS hosting plans are not reliable, so you should study your webhost about uptime guarantee and server management before you place order for your server.
