Putting the "US" in USPS

So... my letter has arrived, but the USPS tracking website bears no updates since the letter first hit India five days ago.

I've since reconsidered my hypothesis. At first I was going to chalk it up to IST or something... now I've decided that USPS apparently does not care about what happens to mail once it leaves the country. It's not "World"PS, after all.

Ah, well. At least the letter reached its destination.
