since friday i can't access ha from work, i thought it was a downtime, but i could access it from home ... so is my ip being blocked? (i'm now sufring by anonymizer)

Does your work have a firewall/router in place? I'd imagine it does. If so, are you absolutely sure that it's not your work that's filtering out hydrogenaudio.org's IP and/or URL and not the other way around? That would be the more likely explanation, IMO.

Perhaps our firewalled blocked you for some reason. If you tried to access HA on another port you would get banned.

Only JohnV and Dibrom can check that though.

i haven't tried to acces it other port, but is a proxy ip, so maybe somebody else (i work at a more than 3000 employees company) ... and it would be very weird to be filtered (HA) ... i'm surfing by anonymouse.com now (anonymizer got greedi ) ... so ... can johnV/dribron check plkease? thanks

Sounds to me like your company's proxy server is blocking access to HA. It's very possible. I know that at my Vocational Technical school I go to they have a proxy and it blocks access to virtually any web site related to video games and even some e-mail web sites such as Yahoo! Mail. Thankfully they haven't blocked HA

ALL YOUR PACKETS ARE BELONG TO US.

BACK TO WORK SLAVE!

-rt

I have exactly the same issue since ... eight months!!!

I sent several e-mails to Dibrom and John V... nothing!

I don't understand.

If I want to access to the site I need to go thru my Gprs (it's so slow and so expensive!!!).

If you work it out also for me, I would appreciate.

Well I can see why the company or organization he works for would block web sites. The company is paying for that Internet connection and they probably want it used for productive means, not as a form of entertainment for employees. They are paying him to work and be productive - not to browse the Internet typing posts in forums.

I'm just trying to think like a company would in this situation. I love surfing web sites I like to visit at school myself so I would be mad if I were in his situation but there isn't much I or he can do about it. Make friends with the computer maintenance people or network administrator. That might get you to HA at work

No blocking IP on my side, it's my own company...

I know that HA filter a range of IP where I'm located, but I really don't know why

part of my job is to researh any new technology ... music is one of them ... but it would be really weird if my company is blocking ... i was never blocked for like 2 years at least ...

Hmmm, well if the blocking of HA is interfering with your job I would tell your company about it and see if they will unblock HA for you.

I cannot access HA sometimes, too. And I have a private provider. I have to disconnect and hope that some other dynamic IP address will be assigned to me (I am behind a DSL). If yes, HA works again for me.

But it is the only website I know of that works this way.

But you're still assuming it is his company blocking HA. We don't know this for sure and since there has been a number of people complaining about a lack of access to the site (not just in this thread) I suspect the problem lies with HA.

I suspect the problem is HA's paranoid firewall.

I'm going to try and work on some server issues, such as tweaking the firewall and handling problems with other 'blocked' users, but I'm really the only one to work on this stuff and I am incredibly busy with school right now (involved in a big conference, papers, finals, etc.).

I probably won't be able to do anything serious until the middle of May or so.

As there is a viable workaround (diconnect until it works, at least for me), there is no real problem. Take your time...

I would not say the same. I really need it for my work. I'm on a big musical/sound/distribution project.
My work around is very stressing (gprs connexion is slooww and $$). I don't really understand why have been blocked eight month ago???

Thanks to enlighten me.

We don't know and Dibrom doesn't have time to check so please be patient as we can't do anything for you ATM.

edit: for the users with problems: can you access the forum when not logged in?
can you access http://doc.hydrogenaudio.org?

Well, the problem is that everytime my IP address starts with 84, I cannot access HA or any other site hosted by HA. I am totally positive that I never tried accessing the site using other ports or whatever.

No such address was banned by us. It must've been an automatic ban.

It it necessary for the firewall to be so sensitive? What if it only banned an IP address for X-amount of time, like 24 hours or something. That would probably be enough to stop any DOS attacks, and might reduce some of the administration work.

edit: With the understanding that it's often not the firewall that is causing the issue. It was for me though.

You block IP 83.xx.xx... I can't access HA whenever I've got IP 83.xx.xx... I have to connect through the proxy server... Why is that happening...

We don't have the 83.* range banned. When did you first have problems accessing HA with that IP?

HA's firewall may block these anyway. IPs in the 83.* range used to be bogus IPs and were released recently. My provider here in France was assigned some of them several weeks ago and since then I haven't been able to connect to HA and several other sites. A French site managed to solve the problem, which was lying in the firewall's source code. Maybe you should investigate this way...

jppie, just want to mentione it: since today i can connect to HA without a proxy by using a 83.* ip.
Thx a lot!

You block IP 65.93.xx.xx , i can't access HA whenever i've got IP 65.93.xx.xx

can somebody remove that auto blocking ?

i have to change my ip address (disconnect and reconnect 2 or 3 times and sometimes more than 10 times)

and that is really starting to irritate me

Sympatico areabans have been there since at least 2002, thanks to strong troll population there.
We're not quite going to lift them, especially not for someone who posted offensive material on our forum before.

Since I started using adsl, I can't reach Hydrogen Audio if I am assigned an IP starting with 85.XX. Than I have to swtich my providers proxy server on like ı'm doing now, which starts with 197.175.
Rarely I'm am asisigned an IP with 212.XX then there is no problem.

OK. but switching the proxy on and off is a problem. (Was a great problem with IE, three cheers for Firefox and its plugins.

Asral

I'm sorry if this is getting repetitive, but I'm going to add myself to the users who cannot access HA from home. My ISP is Verizon DSL. Like other users in this thread, I can connect to HA using a proxy server (which is what I'm doing right now), but never directly. I should add that I encountered the same problem earlier this year when I was using a different, dial-up ISP.

The browser is not the problem; I've tried loading hydrogenaudio.org in Mozilla and Firefox and IE, but they all just time out without loading anything.

It's not a DNS problem; I have no difficulty looking up the correct IP address for HA (209.152.181.169) through my DNS server.

I don't believe it's an intermediate connection issue; a traceroute from my computer to HA timed out after reaching 66.0.192.252, but I did a traceroute from another computer that can access HA, and it also timed out after 66.0.192.252.

I tried contacting my ISP's tech support, but they weren't much help -- the support representative told me that they do not block any sites and that the problem is probably with HA.

After reading this thread, I strongly suspect that the problem is HA's firewall. As far as I can tell, Verizon always assigns me an IP in the 70.* range (currently 70.17.66.xx). I realize that a HA admin explicitly stated about two months ago that 70.* addresses are not banned, but I urge the admins to check the firewall settings again to be sure.

One positive aspect of this situation is that it forced me to finally register as a user on HA after being a casual visitor (aka lurker) for about three years. There's a lot of quality discussion here, and I didn't realize how much I missed it until I was unable to access the site for a few months.

Now I'm been in blocked. My IP is 85.76.xx.xx

And I suppose all the 85 started IP addressed is blocked because I have changed it to other 85-base address without any help. Traceroute shows that the block is in our end.

Could someone have time to check HA firefall settings?

According to what Dibrom said, there are *no* IP ranges blocked on firewall level since last server move. Our hosting provider is having some serious issues.

I tried to say ... Traceroute shows that the block is in YOUR end.


Yep, thats what I thought. Here are last hops in your end what I can see. (Traceroute = www.hydrogenaudio.org)
Maybe some email to edeltacom could help.

Done

Just for notice.
Still blocked and Edeltacom said that problem it's not their routers.
Then it's must be HA server, firewall...

Lots of users are behing 85.xx.xx.xx. Thats pity...

Who should be notified of this?

I had many many problems to access HA. A few months ago, I was using Tiscali adsl in france, I just couldn't access HA or foobar2000 pages. Tiscali told me that they gave me an IP number that was sometimes blocked by some firewalls. Now I'm using Wanadoo, another french provider, and HA's forum told me I wasn't permitted to use this board for several weeks. Now everything works.

Could some administrator in this forum finally check why 85.76.xx.xx started IP addressed is blocked. This really is frustrating.

I do understand you may have busy some weeks, but this situation is absurd. It has been like this about two month now!!!

Please be so kind.

Same issue here when I get an ip starting with 85.* I am getting blocked

85.76.* blocked by the whole server here too.

yeh I'm being blocked unfortunately My isp is Shaw and my ip is in the 70.xx range. Right now I'm using their proxy, but it's slow as hell.

FWIW 85.97.* works fine

I wrote here two months ago about my inability to access HA via Verizon DSL. I am happy to report that I can now connect to HA successfully without having to go through a proxy server. My dynamically assigned IP is different than it was before, but it is still in the 70.17.* range. So if someone did something to fix this, thanks.

We moved to a new server = problems should be solved.

The technical reason is probably that the former server's firewall blocked IP ranges that were marked as "Reserved" by the IANA. But due to the address shortage in IPv4, the IANA has been putting more and more of those reserved ranges into use. As the server's firewalls hadn't been updated, everybody who got an IP in such a new block was left out.

For example, the block 85.x was assigned in July 2004 and 70.x in January 2004.

My IP-range seems to have been blocked for quite a while.

Is it possible you could lift the block? Range: 80.202.*.*

Thanks.

Since several weeks I got a new IP in the range 89.49.xxx.xxx

This seems to have been a "reserved" range before - and I cannot access HA from home. First i blamed my provider freenet.de for this, but they are not guilty this time

Not a problem at our end. Your traceroute already shows this, btw. You don't even get to the server.

I had frequent connection problems with freenet in the past. Unreachable targets and a crawl-like connections to certain countries(i.e. japan) were not an exception, but the norm. After 3 months, i had enough of it, changed to another ISP, and everything suddenly was fine.
