 Good call, that will work for a short-term fix. But then the proxy
 requests will be going through the CDN and cost money.

 Rough cost estimate. CDn traffic [https://azure.microsoft.com/en-
 us/pricing/details/cdn/ costs] minimum $0.08/GB, call it $0.10/GB. Proxies
 poll every 10 s, that's 9000 times per day. Suppose each poll costs 1 KB
 (wild guess including TLS overhead). Then if there are 6 proxies running,
 that's about 0.5¢ per day:
 {{{
 >>> 6. * 9000 * 1024 / 1024 / 1024 / 1024 * 0.100
 0.00514984130859375
 }}}
 If there are 100 proxies, it's about 8.5¢ per day:
 {{{
 >>> 100. * 9000 * 1024 / 1024 / 1024 / 1024 * 0.100
 0.0858306884765625
 }}}
 Of course we could control this by adjusting the polling rate.

 In any case, I'll make sure there is at least $100 in the Azure account in
 case we want to do this for a short-term fix.
