Is there a problem with JCenter?

JCenter regularly has problems, so quite possible. I for example never depend on JCenter forwarding to Maven Central, but always declare both and Maven Central first, so that it is used directly if possible, and release things to MC, so that it is better available and for Maven users without repository declaration.
