Azure Service Bus Support

24/7 Azure Service Bus Support with a 15-Minute Emergency SLA

AceMQ supports Azure Service Bus in production — lock expiry causing duplicate processing, Standard-tier throttling under burst load, dead-letter queues filling from MaxDeliveryCount, and Premium namespaces sized wrong for the actual message profile. Every ticket reaches a named senior engineer who already knows your namespace and entity layout.

Escalation Path

Your first hour of a Azure Service Bus outage

Most vendors publish an SLA number. This is what actually happens, minute by minute, when you page a senior AceMQ engineer.

T+0

You page us

Phone, email, or Slack — any channel reaches the on-call senior engineer directly. No web form, no tier-1 queue.

T+15

Named engineer live

A senior engineer who already knows your environment joins a live bridge. Zero cold-start, no re-explaining your topology.

T+30

Root cause isolated

Direct broker access, log and metric review, and a working hypothesis with a rollback plan before we touch anything.

Post

Written RCA

Documented root cause, the fix applied, and the prevention steps — delivered after every P1, not just when asked.

Response Times

SLA tiers, contractually guaranteed

Every tier reaches a senior Azure Service Bus engineer. There is no tier-1 triage layer to get through.

P1 — Emergency
15 min

Production down, messages not flowing, cluster or broker failure

P2 — Critical
1 hour

Severe degradation, rising error rates, approaching capacity limits

P3 — High
4 hours

Performance issues, configuration problems, non-critical failures

P4 — Standard
Next day

Questions, guidance, best practices, non-urgent improvements

Incident Triage

Azure Service Bus problems we fix every week

These are real symptoms from real Azure Service Bus production environments — and the first thing our engineers check when one comes in.

Messages processed more than once despite PeekLock
What we check firstHandler duration against LockDuration and whether the client is renewing the lock. When processing outlives the lock the message becomes visible again and a second consumer picks it up — the first handler then fails its Complete with MessageLockLostException.
Typical resolutionUnder 1 hour
ServerBusyException and throttling under burst traffic
What we check firstWhether the namespace is Standard tier, which throttles on shared credits rather than reserving capacity. We measure sustained versus peak operations before recommending Premium, because moving tiers without sizing messaging units just relocates the ceiling.
Typical resolution1–3 hours
Dead-letter queue filling steadily with no application errors logged
What we check firstThe DeadLetterReason property on the messages themselves — MaxDeliveryCountExceeded, TTLExpiredException, and HeaderSizeExceeded point at three unrelated fixes. Delivery-count exhaustion usually means the handler is throwing before Complete on a transient dependency.
Typical resolutionUnder 2 hours
Queue depth climbing while consumers appear idle
What we check firstWhether the entity has sessions enabled and the consumer is not accepting sessions, or a competing session lock is held. With sessions, one blocked session ID stalls only its own ordered stream, which reads as partial delivery rather than an outage.
Typical resolution1–3 hours
QuotaExceededException on send, producers failing hard
What we check firstEntity size against MaxSizeInMegabytes, including the dead-letter sub-queue which counts toward the same quota. A DLQ nobody drains will eventually stop the live queue from accepting sends, and the error surfaces on the producer rather than anywhere near the cause.
Typical resolutionUnder 1 hour
Topic subscribers missing messages that were definitely published
What we check firstSubscription filter rules and their evaluation order. A SQL filter referencing a property the publisher stopped setting silently matches nothing, and a default TrueFilter left in place alongside a correlation filter changes which subscriptions receive what.
Typical resolution1–2 hours
Intermittent connection drops from AKS or App Service workloads
What we check firstWhether AMQP over port 5671 is being blocked or idled out by the network path, forcing fallback to AMQP over WebSockets. Idle-timeout behavior in Azure Firewall and NAT gateways is the usual cause and it presents as random reconnects under low traffic.
Typical resolution2–4 hours
Geo-disaster recovery failover completed but consumers stayed down
What we check firstWhether the alias actually swapped and whether entity metadata replicated — Geo-DR pairing replicates entity definitions, not message data. Applications holding a cached connection string to the primary namespace will not follow the alias without a reconnect.
Typical resolution2–4 hours

Resolution times reflect typical Azure Service Bus engagements under an active AceMQ support contract. Every P1 closes with a written root-cause analysis.

What's Included

Everything in your Azure Service Bus support contract

No add-on pricing for incidents. No per-ticket charges. One contract covers the whole surface.

Emergency Incident Response

Producers failing on quota, consumers stalled, or a namespace throttling in the middle of a business-critical window. A senior engineer joins a live bridge within 15 minutes — not a ticket acknowledgement.

Root Cause Analysis

Every P1 closes with a written RCA including the exception types involved, the metric evidence, the fix applied, and the entity or client change that prevents recurrence.

Tier & Throughput Sizing

Standard versus Premium decisions backed by measured operation rates, messaging unit sizing, partitioning strategy, and prefetch and concurrency tuning against your real message sizes rather than a pricing page.

Client & SDK Debugging

Azure.Messaging.ServiceBus, the legacy Microsoft.Azure.ServiceBus SDK, Java, Python, and JMS 2.0 clients — including the lock renewal, retry policy, and processor concurrency settings that cause most duplicate-delivery reports.

Identity, Networking & Compliance

Managed identity and RBAC in place of SAS keys, private endpoints and service endpoint rules, customer-managed keys on Premium, and diagnostic settings that actually capture what you need during an incident.

Migration & Architecture Review

Migration from on-premise MSMQ, IBM MQ, or ActiveMQ into Service Bus, plus honest guidance on when Event Hubs, Storage Queues, or a self-managed broker is the better fit for a given workload.

Why AceMQ

What you get that you don't get elsewhere

Named Engineers, Zero Cold Start

The same senior engineers stay on your account. They know your namespaces, your entity layout, and which workloads sit behind which subscriptions — so a P1 call starts with diagnosis, not orientation.

No Tier-1 Triage Layer

You reach a senior engineer directly by phone, email, or Slack. Nobody collects a repro to pass along, and there is no support-plan tier gate between you and someone who can read your Service Bus diagnostic logs.

The Client Side, Which Azure Support Won't Debug

Most Service Bus incidents are client-side: lock renewal, prefetch, retry policy, or a handler that throws before Complete. Platform support scopes to the service, which means the layer causing your problem is the layer nobody is looking at.

Genuine Follow-the-Sun Coverage

Engineers across 26+ countries and every time zone. Your 3am incident is someone's mid-afternoon — no overnight skeleton crew, no waiting for a region to wake up.

Proactive, Not Just Reactive

Quarterly reviews of dead-letter growth, active message age, throttled-request trend, and entity size headroom — so you catch a subscription filter that stopped matching before it becomes a month of missing data.

We Know the Alternatives Too

We support RabbitMQ, Kafka, IBM MQ, and ActiveMQ at the same depth. That means we will tell you when Service Bus is the wrong tool for a workload, and when Event Hubs or a self-managed broker would cost less and behave better.
