I think you're describing a different phenomenon, traffic jams (smile). |
18 |
That sometimes happens here & may persist for 1 - 2 weeks , |
19 |
but it feels just like driving on the highway when 1 lane is closed. |
20 |
That probably is some piece of the Internet or ISP under repair or test. |

What I'm refering to is getting downloaded files in slices, |
23 |
eg using Wget, a piece of the file downloads for 22 sec , then stops; |
24 |
Wget tries again & another 22 sec piece comes down the pipe, then stops. |
25 |
This can go on for hours with a big file |
26 |
& doesn't seem related to the local time of day. |
27 |
My guess is that the server has been programmed to stop after 22 sec |
28 |
in an effort to share access among many clients, |
29 |
but it is irritating & also suggests the server needs faster hardware. |

31 |
Have others noticed this -- it seems to be a recent innovation -- |
32 |
& is it a known ploy of server managers ? |
