Comment Re:Well I certainly do (Score 2) 445

You can get redundancy.

We do have multiple Asterisk servers on Amazon EC2, each of them can take role of another. Amazon has availablity zones, so if there is problem, it's within single zone, so it's best to have replacement in different zone.

As for ISP - we have several, and as we can control our servers, we can just quickly reroute calls to different ISP in the same office. If all of our ISPs would give us access to switching BGP, it would be even easier.

As our business depends on phone calls heavily, our telephony carrier has granted us use of backup gateway,where they can reroute DIDs within 30 minutes.

So they would just automatically match scenes from other recordings (and knowing which channel it was recorded helps), and keep single copy of every possible difference (ads, logo). Put all that in the nice box of interface for retrieving every individual copy and call it "compression".

Comment As often as you need (Score 1) 182

I work on a telephony infrastructure (voip pbx + websites), and production releases are as often as we need it.

Even if every minute of bugs or downtime costs money in terms of disconnected customers, gain is by being able to react and fix quickly. Sometimes I do write a quick code (usually fix) on live system, of course knowing what you do and what's on the stake makes you pay attention to details, taking a look on semicolons at the end of line before hitting save.

Also having control of replicating changes to all servers is a good tool, you can do a live test on small set of users, and if there are no errors just replicate changes to all servers.

However normal "feature" releases are usually from couple of times per week to once per month, depending on the size of features.
Rollbacks are always in mind, but you can't rollback everything, new call logs and recordings are created live - so either implement some backup of raw data and be prepared to manually fix broken parts later or you may just loose something important.

Comment Re:CA (Score 2) 82

You're getting redundant. How can you secure and verify HSTS origin (to transfer info about allowed CA), if you don't know with whom you established HSTS (there is no authority that has signed it).

Current CA scheme works as it is, because CA information is included in browser, and in order to replace that, there has to be other means to transfer authority information (DNSSEC could theoretically be usable)
