Increase in Barracuda IP blocks

A number of folks are talking about a significant uptick in Barracuda IP blocks over the last few days. These blocks appear to be affecting wide ranges of IPs across multiple networks.

Folks have been reaching out to Barracuda through their unblocking form. Many of them are not receiving answers, but some are getting answers that say they may be old listings, and there is no current data to support the listing.

This issue is ongoing, as I was writing this post another ESP posted that they were seeing widespread listings affecting multiple customers. As of 1500 UTC folks are still seeing listings populate.

I did reach out on Twitter and their CS folks are passing the reports on to the correct people inside the company. Updates as I get them.

Update (1900 UTC): Barracuda support is actively responding to issues on Twitter. If anyone is actually a Barracuda customer, they’d like a case filed with support about this. Posters on mailop say Barracuda is aware of the issue and are trying to fix.

June 19: The blocks should be resolving now. More information on the update blog post.

Delisting at ATT

ATT used to have a webform to use to request delisting. I’ve heard reports over the last few months that the form isn’t working. This week, the website hosting the form disappeared. I don’t know for sure, but this looks like this is either deliberate or there’s just no one in charge of the site and it got lost.
ATT provides an email address for delisting, too. Unfortunately, I’m also hearing they’re not responding to that address. There are two possible reasons. One, they’ve never answered and they just delist or not depending on stats. Two, they’re not monitoring that address, either.
In any case, the delisting isn’t working and I don’t know when it will be. I know some people have contacted ATT reps, so they are aware of the current issues. More as I find out.

Ethics in Internet Operations

In early September, I posted about a survey being done by Jan Schaumann regarding how sysadmins viewed their ethical obligations with regard to users. The results of this have now been published by Jan. He’s also shared his talk and slides on the data.
Well worth a look through the data. I took a quick run through of his talk and it looked interesting and is definitely going on my to-read list.

Use the form…

A lot of senders get frustrated with the time it can take to get a response from some ISPs. It’s totally understandable, for a lot of companies delivery problems are all hands on deck level problems. They want them fixed and they want them fixed IMMEDIATELY. They want feedback that their issue is being addressed. They want to know someone at the ISP knows there is a problem.
I’ve talked before about visiting my friend Anna and watching her laptop screen explode with IMs from senders who wanted help with an AOL issue. She’s awesome and conscientious and tried to address all of those issues as fast as she could. She did want senders to feel like their issues were important and that someone inside AOL cared about the mail blocks.

I was always a strong advocate for following the official pathways for addressing problems. That was the whole point of the 2009 blog post. These days it’s easier to do than it ever was. Many ISPs have forms and process around handling delivery issues. This is good! In the past getting an answer to “why is my mail blocked” required knowing the right people. Now, it’s not about who you know. The ISPs and filtering companies who are open to senders have postmaster pages, unblock forms and official request channels. Those that don’t have those channels have made certain business decisions to not provide support for senders.
Despite the availability of webforms and knowledge bases and detailed information, a lot of people still think that the only way to get attention or get an issue addressed is to get someone on the phone. It’s not, though.
ISPs have their processes. If you want things handled quickly use those processes. Even in the places where very helpful reps are, they can’t (on order of lawyers and executives) help people unless there is a ticket already open.
Always, always use the recommended processes before trying to find “a real person.” Most of the time your issue can be solved faster if you fill out the form than if you hunt around for a person. In the worst case, all that time will be wasted as the person in question will tell you to fill out the form.
