<div dir="ltr">Most VPS have a policy where unused CPU time can be grabbed by other VM users. This means when other servers on the same host are quiet you get more than your fair share. This is a nice bonus but you should not plan on having that available all the time. We monitor steel time to get an idea of how much it's happening: <a href="http://blog.scoutapp.com/articles/2013/07/25/understanding-cpu-steal-time-when-should-you-be-worried">http://blog.scoutapp.com/articles/2013/07/25/understanding-cpu-steal-time-when-should-you-be-worried</a><div><br></div><div>We had problems with DNS before after a Linode attack. We now add Google's DNS servers to our servers on setup. I've just realised as I typed this that you might be thinking the other way round. We don't use our hosts DNS service - use a dedicated company for that (we didn't find Linodes very high quality and it's too important to risk).</div><div><br></div><div>George</div></div><div class="gmail_extra"><br><div class="gmail_quote">On 4 March 2015 at 10:02, David Salgado <span dir="ltr"><<a href="mailto:david@digitalronin.com" target="_blank">david@digitalronin.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div>TL;DR - it's what you should expect.</div><div><br></div>I've been hosting *lots* of VMs on several different hosting providers.

There may be VM hosting companies who accurately limit resources so that one customer never gets an unfair share of the resources of physical host, but I've never found one (and I can't imagine why they would want to, from a business standpoint).</span></div><span class=""><div><span style="font-size:12.8000001907349px"><br></span></div><div><span style="font-size:12.8000001907349px">>> </span><span style="font-size:12.8000001907349px">- We had problems with DNS latency (we are talking seconds here)</span></div><div><span style="font-size:12.8000001907349px"><br></span></div></span><div><span style="font-size:12.8000001907349px">I haven't encountered this problem before, so it's possible it's something that DO suffer from, and others don't. However, the way our architecture works, we don't do many DNS lookups, so the fact that we haven't seen it doesn't really tell you much.</span></div><span class=""><div><span style="font-size:12.8000001907349px"><br></span></div><div><span style="font-size:12.8000001907349px">>> </span><span style="font-size:12.8000001907349px">Each time we found a problem they did not trap it in any kind of monitoring.</span></div><div><span style="font-size:12.8000001907349px"><br></span></div></span><div><span style="font-size:12.8000001907349px">Ditto. I always hear about problems from our own monitoring solutions long before I get alerts from the hosting company (if I ever get them). The lesson is to never skimp on your monitoring. It's also important to have monitoring that sits *outside* your hosted system, to pick up problems with their internet connectivity.</span></div><div><span style="font-size:12.8000001907349px"><br></span></div><div><span style="font-size:12.8000001907349px">David</span></div><div><span style="font-size:12.8000001907349px"><br></span></div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote"><div><div class="h5">On 4 March 2015 at 09:40, Klaus Hebsgaard <span dir="ltr"><<a href="mailto:klaus@hebsgaard.dk" target="_blank">klaus@hebsgaard.dk</a>></span> wrote:<br></div></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div class="h5"><div dir="ltr">Hi<div><br></div><div>I am the developer and siteOp for Be My Eyes.</div><div>Currently we host our site on Digital Ocean (DO) and we are pretty happy with them, they even provided us with at lot of free hosting.</div><div>We have 2 load balancers, 3 web servers and 3 db hosts.</div><div><br></div><div>However we have had a few issues with the VPS'ese on DO.</div><div><br></div><div>- We had some problem with other VPS'ese stealing cpu time from our VPS.</div><div>- We had problems with DNS latency (we are talking seconds here)</div><div><br></div><div>Each time we found a problem they did not trap it in any kind of monitoring.</div><div><br></div><div>So my question is: Is this what we should expect from VPS?
