To the cloud ?
|
I've been working with a small startup, which is aiming to create a phone app similar to uber. Currently, everything is still run on a single server. That is, both our website, as well as the server-side service that our app uses. The guy who originally set this server up has since left, well before I was onboard, so I never even met the guy. I have been hired to be the tech guy in his stead. Point is, I'm admin to a system which I did not set up myself, and for which I am the ONLY admin. Any technical questions I have need to be answered by myself alone. Even the guys making the app itself have little involvement with this server.
A few weeks ago, I had to install a new SSL certificate for our website, as the old one was due to expire. In order to do this, I ran into some technical issues and ultimately had to resort to running windows update to resolve them. There were over 200 updates to be installed, with the last update being over a year ago. This resolved the issue. This is a windows server 2012 R2 system.
A few days later, our website went down. Only the website. Our app's service was uninterrupted, and I was able to remote into the system as well. Once remoted in, I saw nothing wrong. We ultimately tried rebooting the system, and that worked. Subsequent searches of the event viewer and other logs turned up nothing to explain the outage.
This has recurred every few days. Once occurred at 2 AM, while I was asleep, and that let us observe that the problem self-resolved somehow. After about 45 minutes, the website went back up, with no human intervention.
There is no set time in which this happens. Its happened at various points in time, so I don't think its the side effect of any regularly scheduled thing.
The closest I can come up with is that server manager's logs had a sizable chain of ASP.net events throwing unhandled exceptions.
Also, as I mentioned earlier, there were a lot of updates that got installed, I suspect that one of them has thrown something off, but at 200 updates, pinpointing the right one is difficult, and thats assuming that is even the cause.
I doubt its the recently installed SSL certificate, if that was bad then people would be getting unsigned certificate warnings or somesuch, yes? I don't see why such a thing would outright bring down a web page
The site is running on IIS 8.5. The actual physical server is hosted by 1and1 hosting. The fact that the app's service was still working, as was the (interrelated) SQL service would indicate strongly that its not a hardware issue.
