Description Andrey Loskutov CLA 2022-02-21 04:23:07 EST 
Platform builds fail on regular base trying to read some (checked in) files from github repository and fail with zero data received.

See for example

See https://gitlab.eclipse.org/eclipsefdn/helpdesk/-/issues/912#note_570694

Quote:

I just found that raw.githubusercontent.com has a rate limit of about 5000 requests/hour/IP (https://github.com/github/docs/issues/8031#issuecomment-881427112). 
[...]
If the rate limit is the issue and as all Jenkins instances retrieve artifacts from raw.githubusercontent.com from the same public IP address, so there is not much we can do from the EF infra side unfortunately.
Comment 2 Andrey Loskutov CLA 2022-02-22 02:28:26 EST 
Both Linux builds failed again today.
