There have been instances where the number of listeners get into the thousands and the servers can not handle the load, and it will effect the archives.
That has not been the case for a few years.... The last time we experienced a server load issue due to traffic was during the Boston Marathon bombings. That was 3 years ago. The San Bernardino shootings drove far more traffic and we didn't so much as hiccup during that incident.
The simple reality is that the vast majority of our feeds are delivered over consumer grade internet connections which are notoriously unreliable for 24x7 constant streaming. Couple that with consumer grade equipment providing the streams and you have a recipe for archives that aren't going to be guaranteed available 24x7 365 days a year.
Granted, we have a lot of feed providers that provide excellent professional level streams with significant investments in equipment who's streams have for all intents and purposes never gone down.
And yes, there is the rare instance when we have an outage. But seriously, those are extremely infrequent. If you are expecting 100% uptime from any online service, you won't find it. Not on Facebook, not on Bank of America, not on the Wall Street Journal, and not on Broadcastify.
...and finally, and I'll say it again for the 100th time because some people just don't seem to get it. We have NEVER deleted an audio archive at the request of any agency. Meaning, there has never been an instance where we censored an audio archive from Broadcastify.
