Google Drive hosting downloading limit?
google does have bandwidth limitations, by which your account is held to certain standards. overage against these limits can cause a temporary suspension of your account, typically no longer than 24 hrs, as per their FAQ. ---> https://support.google.com/a/answer/1071518?hl=en
Google does not specify any bandwidth limits, or at least I could not find any. But I think google does have some fair usage limits in play and these limitations would be to reduce abuse of the service and again google does not mention it any where, so there might be some other factors that google considers.
Here is another stack overflow question regarding this.
While I was googling for this issue, I found this forum that discussed the google drive bandwidth issue and found a screenshot. So if this screenshot is correct then there must be some limits in placed.
