Variable speed connection and error on a download files

[cortivo]

Hi
Using wget or curl to download files the connection speed varies. For example, the download starts at 7MB/s and, within a few seconds, the speed starts to drop until it reaches Kb/s. Sometimes it goes back to 5MB/s, 7MB/s 8MB/s and sometimes it shuts down. Sometimes the download occurs normally. I can't understand why. It occurs with any file in the list. A single connection is made per IP. Follow the wget line and into the txt file has a list of files to be downloaded including the url. The connection comes from an IP 150.163.***.*** ... Is an IP with that beginning on a block/black list?

Thanks.
Fabio.
