        The console is quite slow, but it's a console connection. Not exactly like you should have high expectations. However, for me, even the RDP was a bit more sluggish than I'd expect...

          SSH was slow, not the console

            In what way are you seeing SSH as slow? I see some IO performance issues, but those are mentioned as being addressed on the announcements page - they've exhausted their IO. When IO is not being hit, performance seems just fine.

            What OS are you running? Check a SAR report and see if IOWait states aren't the issue.

                Depending on how many updates it had, that's quite possible.

                  I'm also having trouble with my [email protected] Dev1 box. I'm unable to connect via SSH, Yum install via web console throws errors, etc.

                    I wonder if there's a DDoS in progress. Maybe I pissed of the folks in HK when I blocked all of their SSH attempts in iptables? :open_mouth:

                      @thanksajdotcom There was 166 updates, but it did this same thing yesterday, and the updates took less then a minute, both Dev1 boxes. Something is up,

                        That's slow but not crazy. Which OS are you using? It is a big operation with a lot of stuff to download, then to setup in the database, then to roll out one package at a time. Updates really can take a bit of time. Fifteen minutes seems long, but if there is any IO issues, then it would slow down a lot.

                          Could be the IO issues that they list on their site. But it could be more network problems with Rogers, too.

                            Did SSH work before? Or is this a new build?

                              Oh you know what, is everyone having login problems using Ubuntu instead of CentOS? I've seen that issue too.

                                I got some huge delays just typing to the console. Like 30 seconds for a line that I was typing to continue.

                                  I'm checking the Ubuntu instances and am seeing issues around passwords failures in the auth.log.

                                    Looks like you just need to run pwconv after creating a user on Ubuntu 14.04.02. That's all. Works fine once you do that.

                                      As I suspected, it's IOWait problems. Always check SAR first for performance problems.

                                        I'm seeing rather large IO delays here too.

                                          So far I've only seen the IO issues on the Dev1 instances.

                                            I wonder why?
