Vector basemap doesn't show labels, and tile 404 errors

Using the 4.14 Javacript  API, I have a simple page set up with a map uses a vector basemap like so:

 

var map = new Map({
  basemap: "topo-vector",
  layers: mask
});

 

I'm using the basic claro/light css styles:

 

 <link rel="stylesheet" href="https://js.arcgis.com/4.14/dijit/themes/claro/
claro.css" />
<link rel="stylesheet" href="https://js.arcgis.com/4.14/esri/themes/light/
main.css" />

 

with no additional styles applied to my map or view.

 

 

As of this morning, labels are no longer showing up, and as users pan and zoom, several tiles are failing to load with 404 errors.

 

If I switch the code to use a non-vector basemap, everything seems to work properly. And when I view the basemap in the arcgis online viewer, the labels appear fine.

 

status.arcgis.com reports normal operation for basemaps and I didn't change my code between when it was working and now. Is anyone else having issues with vector basemaps? Am I missing some kind of style declaration that's required to show labels?
