If this is a DHL to USPS hand off, such mailing are placed in a trailer until enough of these handoff accumulates, then it gets taken and delivered by the post office.
It isn't that your item is being delayed, these type of handoff just don't get handled the same way regular USPS shipping does. It is much slower and I wonder sometimes why the item wasn't just taken to USPS to begin with. A lot of booksellers use this DHL service, too. The "traveling" shipping pattern is unfortunately normal. Seen a lot of it myself this season.
By contrast, if I select DHL for shipping from overseas, the tracking stays up to date and my things arrive with amazing speed. Of course, that's also when the rates are extremely expensive so I don't do it often.
You'l get your RAM, the wait is frustrating but it'll show up. I've noticed that USPS tracking isn't updating as it used to either. I have two packages that have been in "in transit to next facility" for days. No reason given and the daily emails aren't showing up either.
You're not alone and you have my sympathy! Be patient.
