This is the status of the problem in the picture
Based on my understanding, 'Connecting' can be due to many things. The most common reasons are
Your internet connection is unstable
You become idle* and the session was disconnected
*Either you are away from keyboard or you are doing something else instead of looking at the colab tab.
For 1, you can try using a different internet connection and see if that improves.
For 2, you can either move your mouse every now and then in the colab tab to prevent yourself from becoming idle.. or you can consider subscribing a premium version colab which help with that situation in theory.

I have been getting some emails from AWS with warnings about usage of AmazonCloudWatch alarms (image attached also):
Apparently I have used 8.6 so far this month, but after trying to find out exactly what alarm I have enabled that is triggering I am coming up short. Can anyone advise how to find out what these alarms are and how to turn them off?
Many Thanks
I am unable to access Google Cloud DNS page.
All it shows is:
"DNS API is being enabled. This may take a minute or more."
Then it reloads and repeats showing the same message.
The API is already enabled, and the records I created works. No problem with DNS.
I need to modify records, but I can't because of this problem.
I tried opening the page in different computers and different browsers without addons, same result.
If there is a better place to ask, please do tell.
Thank you.
You should be able to access the page regardless of what computer / browser you're using.
If you cannot it's either a temporary outage which you can check here or a bug.
The only thing to do here is to contact paid support for more immediate help and if the time is something you can afford report this at Google's IssueTracker and get help for free - however it may take a few days. It is possible that only you are affected. Please describe the issue in as much detail as possible - this will expidete the process.
I am using an EC2 instance as a backend database server that receives open listings for an AirBnB type site. I've checked on my own browsers and phones and had others check on theres in other regions as well, and these listings load perfectly fine for us. There is one person in another region, however, who is not seeing any listings at all and receives the Failed to load resource: net::ERR_CONNECTION_RESET error instead. I even had them try clearing their cache in Chrome, but that did not help. Below are photos depicting the situation:

What I See/What Should Show Up:
Black Listings Come Up For Them
Here Are The Errors They Receive
Here are the Inbound settings for my security group
I'm thinking it may be a firewall issue, but i'm just not sure. Any help would be greatly appreciated, thank you!
i would suggest you check the security group in which your machine is, since it's possible that you're not allowing traffic to reach your machines.
it's possible that your location IP is open to the API but not other IP's.
I've tried to reach your page from my place and it's timing out as well, that points to the security group.
if possible share a screenshot of the security group set up on your machine, that will help diagnose further.
So I ran into a network problem the other day and I was trying to find a way to test for this problem in the future.
I had a lot of users online at once and hit my routers max IP connection limit (not DHCP! TCP/UDP connections.)
Once I figured out what the problem was it was fairly simple to fix however I was wondering if there is any way to simulate this kind of activity? Everything worked fine when I tested it, it wasn't until I had 150+ users that I discoved I had a problem.
I have spent the last 3-4hrs looking for such a test/audit tool. Here is what I found:
http://bittwist.sourceforge.net/ -DDoS simulator (can't make it work, barly get +300 connections)
http://stevesouders.com/hpws/max-connections.php -Browser concurrent connection tester (This hits the browser limit (6 in chrome) w/o making a dent on my router even open in 70+ tabs at the same time)
http://www.smallnetbuilder.com/lanwan/lanwan-howto/31103-how-we-test-hardware-routers-revision-3 -Some tool linked about halfway down the page (Reads like its exactly what I want, however it barely has a noticable effect on my router.)
http://www.http-kit.org/600k-concurrent-connection-http-kit.html -Concurrent HTTP connection simulator (This one seems like it would do what I want, but my linux-foo is limited and I can't get it working. tear)
So do you guys have a tool to test your routers with? I would love something that does both TCP/UDP.
(btw, for anyone misunderstanding I'm not trying to test "speed", just sheer number of connections)
Thanks!

I am trying to write a VPN app using VpnService. I started my app based on the sample ToyVpn. It seems to work fine but I am wondering if there is a way to get rid of the pop up dialog when I click connect. I am hoping that I could just click "connect" and it would start without having to click the "I trust this application..." check box and "Ok".
Thanks.
I don't think it's possible. They seem to be very careful about this class. If you take a look at the documentation you can see it says:
Letting applications intercept packets raises huge security concerns. A VPN application can easily break the network. Besides, two of them may conflict with each other. The system takes several actions to address these issues. Here are some key points:
User action is required to create a VPN connection. [emphasis mine]
There can be only one VPN connection running at the same time. The existing interface is deactivated when a new one is created.
A system-managed notification is shown during the lifetime of a VPN connection.
A system-managed dialog gives the information of the current VPN connection. It also provides a button to disconnect.
The network is restored automatically when the file descriptor is closed. It also covers the cases when a VPN application is crashed or killed by the system.
Since it says that user action is required to create the VPN connection, I assume they mean this is something you cannot control yourself.
