I’m having problems updating packages, [status.julialang.org](http://status.julialang.org) takes a long time to respond, sometimes doesn’t respond, it does say that things are operational, but the detailed graphs show lots of red bars for a while now.
Further useful info perhaps:
Not able to ping [us-west.pkg.julialang.org](http://us-west.pkg.julialang.org):
```julia
dlakelan@tintin:~$ ping us-west.pkg.julialang.org
PING us-west.pkg.julialang.org(2600:1f13:a21:3e00:e267:cc2f:ada8:f580 (2600:1f13:a21:3e00:e267:cc2f:ada8:f580)) 56 data bytes
^C
--- us-west.pkg.julialang.org ping statistics ---
6 packets transmitted, 0 received, 100% packet loss, time 5098ms
```
whereas pinging say [google.com](http://google.com) works fine so it’s not like I have no internet, or no working ipv6
```julia
dlakelan@tintin:~$ ping us-west.pkg.julialang.org
PING us-west.pkg.julialang.org(2600:1f13:a21:3e00:e267:cc2f:ada8:f580 (2600:1f13:a21:3e00:e267:cc2f:ada8:f580)) 56 data bytes
^C
--- us-west.pkg.julialang.org ping statistics ---
6 packets transmitted, 0 received, 100% packet loss, time 5098ms
```
ping4 of hte package server doesn’t work either:
```julia
dlakelan@tintin:~$ ping4 us-west.pkg.julialang.org
PING (52.24.172.208) 56(84) bytes of data.
^C
--- ping statistics ---
4 packets transmitted, 0 received, 100% packet loss, time 3080ms
```
(of course, maybe you’ve just configged it not to respond to pings?)

The main symptom from Julia is that `]update` leads to:
(@v1.6) pkg\> update
Updating registry at `~/.julia/registries/General`
which hangs for tens of minutes.

I deleted .julia/registries/General and did a ]update it’s now been doing:
```julia
Installing known registries into `~/.julia`
```
for quite a while, we’ll see, this might be something specific to me or my system, but the fact that those history graphs show so much red and that [status.julialang.org](http://status.julialang.org) doesn’t respond some of the time seems suspect

Yeah it is strange that the status page says “operational” when there are so many red bars.
I’ve rebooted most of the Pkg servers. I’ve also rebooted the machine that `status.julialang.org` runs on.

Instead of pinging the Pkg servers, you can try navigating to them in a web browser.
For example, I just tried going to `https://us-west.pkg.julialang.org` in a web browser, and I received the following message:
> You have reached a [Julia](https://julialang.org/) package server. It is not meant for browsing but for serving resources required by Julia clients to install packages. To discover and explore the Julia package ecosystem, see [this page](https://julialang.org/packages/) for a list of services.
This indicates that my machine is able to successfully reach the `us-west` Pkg server.

Anyway, you could try getting the registry from Git instead of from the Pkg server:
```julia
julia> ENV["JULIA_PKG_SERVER"] = ""
julia> import Pkg
julia> Pkg.Registry.rm("General")
julia> Pkg.Registry.add("General")
julia> Pkg.Registry.update()
```

Yeah, I’m doing something like that now. I believe that it’s taking forever and a day.
When I hit [us-west.pkg.julialang.org](http://us-west.pkg.julialang.org) in my browser, it has connection timed out… retrying it eventually responded after about 40 seconds. But then a second try, and it timed out again.

Just double-checking: you’re not behind any kind of firewall or anything like that, right?

Nothing that is filtering [us-west.pkg.julialang.org](http://us-west.pkg.julialang.org) for example. It did just load finally. Basically it seems intermittent. It responds maybe one out of 4 or 5 times I try to connect and when it does respond it takes tens of seconds to do so.
All my normal web browsing and access to everything I do normally (such as [discourse.julialang.org](http://discourse.julialang.org)) is working fine.

But you are behind some kind of firewall, right?
Can you try from a different machine that is not behind any kind of firewall whatsoever?

I’m not able to reproduce the results that you are seeing. `https://us-west.pkg.julialang.org/` loads for me every time, and within a few seconds.
We probably need more data. To other people reading this thread: can you try going to [https://us-west.pkg.julialang.org](https://us-west.pkg.julialang.org) in your web browser and seeing if it loads, and if so, how long it takes to load.

I have a router, so yes. Every sane person is behind some kind of firewall. No one just plugs their laptop directly to their cable modem or whatever. The best I can do is try to grab it from my phone with wifi turned off, but that will not be primarily testing the firewall it’ll be testing the difference between ATT connectivity and T-Mobile connectivity.
from my phone on t-mobile it replies within 3 to 5 seconds.
It’s very possible that there’s an issue with ATT connectivity to the servers. However, notice the output from mtr:
```julia

```
Shows that the last hop before the server gives 0% packet loss and avg 7.2 ms ± 4.6ms of ping, so I don’t think there’s a route issue. (the intermediate nodes showing packet loss is just due to people down-prioritizing pings on core routers etc)
Also nothing about my firewall would be causing those red bars on [status.julialang.org](http://status.julialang.org)
Also I was finally able to accomplish a pkg update, it took about an hour.

Yeah I think there are two different questions here:
1. Why is `status.julialang.org` showing so many red bars? In particular, why is the status page showing red bars for servers that I am able to reach from my machine.
2. Why is your machine having trouble connecting to the `us-west` package server?

Exactly. All I can tell you is that to the extent that there’s a problem connecting, it’s 100% to the package servers, everything else I try to connect to is totally fine.

Interesting.
The `us-west.pkg.julialang.org` machine is hosted by AWS. Specifically, it is located in one of the AWS regions in the western United States.
But looking at the AWS status page ([https://status.aws.amazon.com/](https://status.aws.amazon.com/)), I’m not seeing any relevant outages.

Oh, interesting… maybe this has something to do with IPv4 versus IPv6.
I do not have IPv6. Does anyone else in this thread have IPv6?

Testing with curl, IPv4 works fine, but IPv6 just hangs. I’m on Google Fiber, and a public IPv6 test website shows my IPv6 as functioning normally.
