test without data : failure of webpagetest of the site?

[abioneperhobby]

Hi,

i use webpagatest to check a website.

i check the same page every time.

normally, the test contains, in firstView, results data.

sometime, firstView is null

example :

Code:

runs: {
1: {
firstView: null
},
2: {
firstView: null
}
}

is this a webpagetest problem or a website problem?

secondary, webpagetest bandwith is guaranteed?

thanks.
