comment markdown2pdf latex error
Yes, t2a is for Cyrillic. This answer is a bit old -- these days I'd advise using xetex, which would also solve your multilingual problem. If you take current pandoc's output and run through xelatex, it may even work without any modifications.

comment Getting information from an armored gpg public key file
This is awesome! And kudos to a fellow Haskeller Kazu :) BTW, pgpdump is packaged by Debian (and possibly other distros, too), so check it in the repositories before compiling it yourself.

comment Get rid of “seen” messages at GMail
@terdon: but why does GMail offer those Y messages for download, if they have been downloaded before? I'd like to get rid of the log messages, but first of all to understand what's going on.

comment Large delay when fetching a page from a particular site
@harrymc: it's very simple, actually. My ISP's DNS servers that are responsible for reverse DNS are down. So, attempts to do reverse resolving time out. Try this: dig +trace -x 80.90.233.38. I'm 95% sure that this is the cause, just waiting for confirmation that hackage indeed performs reverse DNS lookups.

Etag is irrelevant, since I use curl for testing. Anyway, the answer about reverse dns is most probably the correct one.

This looks very plausible! Let me verify it.

Now, the ISP problem indeed looks like the only plausible solution, but what kind of problem can it be? They probably do not even suspect about the existence of hackage, so it can't be intentional. If I tell them, "hey, this one site doesn't work for me (but all the others do)", they won't listen.

1. This is the same for all hackage pages. 2. As I said, I tried this on several computers and with several routers (and without one). 4. The problem doesn't exist if I use another ISP in my area.

When using a proxy the problem goes away. Your other suggestions are already addressed in the question itself.

@artistoex: actually, it's possible to use tcpdump to read the pcap file: serverfault.com/questions/38626/…

@artistoex: To avoid decoding TCP packets, you can do the following: in Wireshark, Menu->Analyze->Decode As..., then choose the Transport tab and click on "Do not decode" on the left side. Or I can give you tcpdump output, but you'll have to give me the exact command line (and that command line should do filtering based on the ip address — otherwise there will be a lot of noise).

@artistoex: here you go. It's more or less the same.

@JulianKnight: let me repeat — CSS is irrelevant here, and we're talking about a 30 seconds delay for a single HTTP request.

@JulianKnight: that's right, and it contains all the information that in principle exists about that session. What kind of information do you need in addition to that? GMetrix has a lot of noise, since it is concerned with all the CSS and JS and whatnot, while I'm showing a single retrieve of a bare HTML page (using curl). Also, GMetrix seems to retrieve the page from its own server (it says "Vancouver, Canada"), so it's not surprising that it doesn't see the problem. Anyway, since you insist, here's the link I got: gtmetrix.com/reports/hackage.haskell.org/UWb2TnC5.

It doesn't seem to be MTU. I tested this by connecting directly via ethernet and setting mtu to 1000. The problem persisted.
