For anyone having still having problems with the downloads, we have an official mirror set up now. Please DO NOT download Firestorm from any other sources. We have already seen several malicious download links to copybot viewers being passed out inworld and attempts to post them in comments here.
Simply going to say that despite the overwhelmed server, I downloaded FS 5.0.1 from the mirror server and the installation was as quick and easy as any sane person could wish. So far, the viewer has run flawlessly, despite only uninstalling to 4.7.9 app. Full kudos to the developers, another fine job!
Ben-To download torrent
OMG I have never had too say it before. but the new update is the WORST. I used to log in with no issues and after downloading the new update i cant move, i had to take off every hud and still cant move a single inch even relogging 15 times dosent help.
To rule out a bad install, please logout of the viewer & uninstall the Firestorm 5.0.1 viewer the usual way through Windows Programs & Features in control panel and download the installer again from & run the installer.

This document applies to the first version (i.e. version 1.0) of the BitTorrent protocol specification. Currently, this applies to the torrent file structure, peer wire protocol, and the Tracker HTTP/HTTPS protocol specifications. As newer revisions of each protocol are defined, they should be specified on their own separate pages, not here.
The tracker is an HTTP/HTTPS service which responds to HTTP GET requests. The requests include metrics from clients that help the tracker keep overall statistics about the torrent. The response includes a peer list that helps the client participate in the torrent. The base URL consists of the "announce URL" as defined in the metainfo (.torrent) file. The parameters are then added to this URL, using standard CGI methods (i.e. a '?' after the announce URL, followed by 'param=value' sequences separated by '&').
As mentioned above, the list of peers is length 50 by default. If there are fewer peers in the torrent, then the list will be smaller. Otherwise, the tracker randomly selects peers to include in the response. The tracker may choose to implement a more intelligent mechanism for peer selection when responding to a request. For instance, reporting seeds to other seeders could be avoided.
Implementer's Note: Even 30 peers is plenty, the official client version 3 in fact only actively forms new connections if it has less than 30 peers and will refuse connections if it has 55. This value is important to performance. When a new piece has completed download, HAVE messages (see below) will need to be sent to most active peers. As a result the cost of broadcast traffic grows in direct proportion to the number of peers. Above 25, new peers are highly unlikely to increase download speed. UI designers are strongly advised to make this obscure and hard to change as it is very rare to be useful to do so.
By convention most trackers support another form of request, which queries the state of a given torrent (or all torrents) that the tracker is managing. This is referred to as the "scrape page" because it automates the otherwise tedious process of "screen scraping" the tracker's stats page.
The scrape URL may be supplemented by the optional parameter info_hash, a 20-byte value as described above. This restricts the tracker's report to that particular torrent. Otherwise stats for all torrents that the tracker is managing are returned. Software authors are strongly encouraged to use the info_hash parameter when at all possible, to reduce the load and bandwidth of the tracker.
A block is downloaded by the client when the client is interested in a peer, and that peer is not choking the client. A block is uploaded by a client when the client is not choking a peer, and that peer is interested in the client.
It is important for the client to keep its peers informed as to whether or not it is interested in them. This state information should be kept up-to-date with each peer even when the client is choked. This will allow peers to know if the client will begin downloading when it is unchoked (and vice-versa).
The initiator of a connection is expected to transmit their handshake immediately. The recipient may wait for the initiator's handshake, if it is capable of serving multiple torrents simultaneously (torrents are uniquely identified by their infohash). However, the recipient must respond as soon as it sees the info_hash part of the handshake (the peer id will presumably be sent after the recipient sends its own handshake). The tracker's NAT-checking feature does not send the peer_id field of the handshake.
Implementer's Note: That is the strict definition, in reality some games may be played. In particular because peers are extremely unlikely to download pieces that they already have, a peer may choose not to advertise having a piece to a peer that already has that piece. At a minimum "HAVE suppression" will result in a 50% reduction in the number of HAVE messages, this translates to around a 25-35% reduction in protocol overhead. At the same time, it may be worthwhile to send a HAVE message to a peer that has that piece already since it will be useful in determining which piece is rare.
The bitfield message is variable length, where X is the length of the bitfield. The payload is a bitfield representing the pieces that have been successfully downloaded. The high bit in the first byte corresponds to piece index 0. Bits that are cleared indicated a missing piece, and set bits indicate a valid and available piece. Spare bits at the end are set to zero.
View #1According to the official specification, "All current implementations use 2^15 (32KB), and close connections which request an amount greater than 2^17 (128KB)." As early as version 3 or 2004, this behavior was changed to use 2^14 (16KB) blocks. As of version 4.0 or mid-2005, the mainline disconnected on requests larger than 2^14 (16KB); and some clients have followed suit. Note that block requests are smaller than pieces (>=2^18 bytes), so multiple requests will be needed to download a whole piece.
View #1In general peers are advised to keep a few unfullfilled requests on each connection. This is done because otherwise a full round trip is required from the download of one block to begining the download of a new block (round trip between PIECE message and next REQUEST message). On links with high BDP (bandwidth-delay-product, high latency or high bandwidth), this can result in a substantial performance loss.
The super-seed feature in S-5.5 and on is a new seeding algorithm designed to help a torrent initiator with limited bandwidth "pump up" a large torrent, reducing the amount of data it needs to upload in order to spawn new seeds in the torrent.
When a seeding client enters "super-seed mode", it will not act as a standard seed, but masquerades as a normal client with no data. As clients connect, it will then inform them that it received a piece -- a piece that was never sent, or if all pieces were already sent, is very rare. This will induce the client to attempt to download only that piece.
When the client has finished downloading the piece, the seed will not inform it of any other pieces until it has seen the piece it had sent previously present on at least one other client. Until then, the client will not have access to any of the other pieces of the seed, and therefore will not waste the seed's bandwidth. 2ff7e9595c
