My application consists of three applications, and everyone of them runs in its own Docker container.
To reduce build times, I tried docker-compose build --parallel today – with a very undesired effect: The server serving warehouse.meteor.com (94.31.29.131) blocked my IP address completely. No HTTPS, even no ping is possible at the moment. This server contains all the Meteor packages.
Fortunately, I could change my IP address temporarily to another one in the same subnet, so I could finish the build.
I just want to inform you, before the same happens to you.
