4G coverage problems in zip code 90077 Los Angeles

I used to get good 4G coverage at my home: 10 Mbps download and 6 Mbps upload.  Since mid-May 2014, data coverage has been mostly non-existent.  Occasionally get 3G coverage at 500 Kbps down and 80 Kbps up, but spotty.  Devices work fine on 4G network in other areas so this seems to be a local problem.  Affects 3 iPhones, 1 iPad, 1 Ellipses, 1 Galaxy S4 and a Mifi, which all work fine in other locations, so I doubt it is a device issue.

Anyone else experiencing this?
