Managed infrastructure · Ulaanbaatar
Ulaach manages corporate email, DNS, servers, databases and the automation that connects them — for companies that need this to work every day but do not want an in-house infrastructure team.
Services
We take responsibility for a defined part of your technical estate and keep it running — not a one-off project that ends when the invoice is paid.
Company mailboxes on infrastructure we run and monitor, with the authentication that decides whether your mail is trusted by the recipient.
Authoritative nameservers and zone management, so records change when your business needs them to rather than when a reseller gets around to it.
Linux servers on cloud or on-premises hardware, patched, monitored and documented, with someone accountable when something stops.
Production database care for systems the business cannot afford to lose — capacity, performance and a backup strategy that has actually been tested.
The repetitive work between systems — reports, transfers, reconciliations — handled by something that runs on schedule and tells you when it doesn't.
Backups that are scheduled, verified and restorable — and a recovery procedure someone has walked through before the day it is needed.
How we work
Most of the risk in managed infrastructure sits in the handover. We move deliberately at the start so that the running phase is uneventful.
We document what exists today — servers, domains, mail flow, backups — and write down what is fragile before anything is touched.
Systems move one at a time, lowest risk first, each one verified and watched before the next follows. Nothing is cut over in bulk.
Monitoring, patching, backups and capacity checks run on a schedule, with alerts that reach a person rather than a dashboard nobody opens.
You get a plain account of what changed, what broke, what it cost and what we intend to do about it next month.
Sectors
Established Mongolian businesses with real operational dependence on email and internal systems, and no reason to employ a full infrastructure team.
Field reporting, drilling documentation and correspondence with contractors and regulators — where a mailbox failing is an operational problem, not an inconvenience.
Clinic and laboratory correspondence with patients, partners and suppliers, handled with the confidentiality the sector requires.
Firms exchanging financial documents with clients, where message delivery and record retention both have to be dependable.
Operational correspondence across time zones and partners, on infrastructure that does not go quiet outside office hours.
Editorial platforms and the content pipelines behind them, including scheduled publishing and distribution.
Small and mid-sized firms consolidating scattered hosting, domains and mailboxes into one managed arrangement.
Email practice
Everything leaving our infrastructure is correspondence between parties who already have a relationship — an invoice, a system notice, a reply to a customer. We publish how we operate because deliverability depends on it, and because our clients are entitled to know.
Employees, customers, vendors and partners of the companies we host. We do not buy, rent or scrape mailing lists, and we do not send unsolicited commercial mail.
A domain is verified and configured with SPF, DKIM and DMARC before it is permitted to send anything through our infrastructure.
Every mailbox carries an hourly sending cap sized to what that person actually needs, so a compromised password cannot become a mass send.
Delivery failures are monitored. Addresses that hard bounce are identified and taken out of use rather than retried indefinitely.
Complaint and reputation signals are routed to our operations alerts. An account showing abnormal behaviour is restricted while we investigate.
Reports reach a monitored address and are followed up with the account concerned. Write to abuse@ulaach.net.
About
Ulaach is an infrastructure practice based in Ulaanbaatar. We work with a limited number of clients so that the person answering your message is the same person who configured the system.
Our background is production operations rather than sales: database administration on systems that run around the clock, server estates that have to survive their own maintenance windows, and the unglamorous automation that keeps the two connected.
We take on new domains slowly and on purpose. Each one is migrated, verified and watched for a while before the next follows.
Contact
Whether you are consolidating scattered hosting, moving away from a provider that has stopped answering, or receiving mail from a domain we operate — this reaches the same small team.
